THR_33 (project)

THR_33 (Tea House for Robots) is comprised of a responsive architectural environment and a group of robotically-enhanced domestic appliances. Imagine if your radio could tune into any frequency that had ever been broadcast. What would we hear? Imagine if your toaster could remember how you liked your toast, or your entire family’s preference. What if your kitchen mixer could prepare ingredients based on downloadable techniques and recipes – where you just choose the recipe/technique, add the ingredients and it does the rest? What if household appliances in the future instead of plugging in to wall outlets recharged at solar powered light wells and required time to play in order to learn. THR_33 imagines all this and proposes that as our appliances become smart we will change the way we live and come to think of them. Perhaps we would cherish these products more than the throwaway gadgets we currently create. In our speculative future, appliances have evolved to become part of the family. THR_33 questions how we will relate to these autonomous and responsive environments and appliances. THR_33 mixes the sophistication of contemporary smart and super phones, with the design aesthetic of iconic industrial products to produce appliances we want to live with. The home will also be transformed. Domestic space will also change to regulate temperature, lighting and produce and store all its inhabitants’ energy needs. These power stations can form a dual purpose – providing power and providing space for the robots and their owners to interact and play.

The 'Tea House' Structure
Conforming to the traditional dimensions of a Japanese Tea House of 9’ x 9’ x 6', the space provides a series of interactions between user and space, space and robots.

Undisciplinarity (essay in book)

The book that resulted from the 'inter_multi_trans_actions: emerging trends in post-disciplinary creative practice' symposium at Napier University in Edinburgh, Scotland on Thursday 26 June, 2008 is nearing publication.

The book 'Digital Blur: Creative Practice at the Boundaries of Architecture, Design and Art' edited by Paul Rodgers and Michael Smyth will now be published by Libri Publishing following Middlesex University’s decision to close Middlesex University Press.

According to Amazon the book is due on 31 March, 2010.

The book contains an essay by Julian Bleecker and myself that is preambled thus:

Marshall and Bleecker, in their essay, propose the term “undisciplinary” for the type of work prevalent in this book. That is, creative practice which straddles ground and relationships between art, architecture, design and technology and where different idioms of distinct and disciplinary practices can be brought together. This is clearly evident in the processes and projects of the practitioners’ work here. Marshall and Bleecker view these kinds of projects and experiences as beyond disciplinary practice resulting in a multitude of disciplines “engaging in a pile-up, a knot of jumbled ideas and perspectives.” To Marshall and Bleecker, “undisciplinarity is as much a way of doing work as it is a departure from ways of doing work.” They claim it is a way of working and an approach to creating and circulating culture that can go its own way, without worrying about working outside of what histories-of-disciplines say is “proper” work. In other words, it is “undisciplined”. In this culture of practice, they continue, one cannot be wrong, nor have practice elders tell you how to do what you want to do and this is a good thing because it means new knowledge is created all at once rather than incremental contributions made to a body of existing knowledge. These new ways of working make necessary new practices, new unexpected processes and projects come to be, almost by definition. This is important because we need more playful and habitable worlds that the old forms of knowledge production are ill-equipped to produce. For Marshall and Bleecker, it is an epistemological shift that offers new ways of fixing the problems the old disciplinary and extra-disciplinary practices created in the first place. The creative practitioners contained within the pages of this book clearly meet the “undisciplinary” criteria suggested by Marshall and Bleecker in that they certainly do not need to be told how or what to do; they do not adhere to conventional disciplinary boundaries nor do they pay heed to procedural steps and rules. However, they know what’s good, and what’s bad and they instinctively know what the boundaries are and where the limits of the disciplines lie.

SmartSurfaces 1.0 Complete

The University of Michigan SmartSurfaces course is now complete. It was a collaborative, project-based learning experience in which undergraduate artists, designers, architects and engineers came together to build physical systems and structural surfaces that have the capability to adapt to information and environmental conditions.

The course was broken into two phases: an introductory / skill building phase, and the final project. For the first part of the course, participants focused on problem and constraint definition, structured brainstorming and skill building. Final teams were assigned in week six and the rest of the semester involved the production of the fully realized, funded projects shown below. Both phases focused on multidisciplinary, collaborative teams to carry out the assignments and projects. An important aspect of this course was the manner in which useful cross-fertilization emerged in the application of different disciplinary methodologies in response to concrete problems in practice.

Course participants had the opportunity to gain experience with using diverse tools and processes. Where possible, learning made use of practical problem solving through experimentation. All participants were challenged beyond their usual intellectual and disciplinary boundaries and had to negotiate and manage differences between the cultures of three university units (Art & Design, Architecture and Materials Science Engineering).

Each team was required to design, build, program and test a ‘heliotropic smartsurface’ that made use of:
• Solar energy harvesting
• Microcontroller programming (with Arduino) and circuit building
• Parametric modeling (with Digital Project)
• Digital fabrication

The teams had to consider and negotiate what makes a surface smart, and why we would be interested in a smart surface that follows the Sun. They had to engage a methodology of defining explicit relationships, complex behaviors, and unforeseen responses in a context of distributed authorship.

This is what they came up with:



The Shy Solar Array: An Adaptive Solar Array That Responds To Weather
Arrays of solar cells are vulnerable to their surroundings, do not maximize the sunlight-collecting surface area, and are unattractive. Inspired by the Mimosa Pudica plant and its tendency to shy away from external stimuli, our shy solar array was created. Our solar array protects itself from damaging elements such as snow or rain by flipping away from them. This will allow the solar array to be implemented in less than ideal weather locations, such as Michigan. Our solar array also maximizes the sun collecting surface area through its unique shape. The form of the array lends itself to a more efficient use of surface area by avoiding shadowing when the cell is rotated towards the sun. Also, the array stands out as a more desirable object that can serve as a stand-alone artifact as well as a useful solar array. Outside of the gallery this solar array would be implemented onto the rooftop of Michigan Engineering buildings as an alternative energy source. To further maximize the collected energy, the solar array should contain solar cells that are specially shaped to the design.

The iWall Modular Light-Filtration System
The wall you see here is a modular, scalable, self-adjusting multi-aperture window, designed to optimize light flow into a room by manipulating the position of rotating wood panels. You could call it an 'automatic venetian blind', as that is the gist of the purpose. The system consists of 30 individual modules, with one panel per module, which allow a variable amount of light to pass through. The structural elements are built modularly, but circuitry elements - such as wiring - are set up in a non-modular fashion. Individual module apertures open and close in reaction to the intensity of the light that passes through the wall as detected by light-dependent resistors (LDRs), seen on the projection side, holding a relatively constant light level on the ‘interior’ of the wall at all times - this gives 'heliotropic' and 'smart' characteristics to the wall - 'surface', fitting it into the premise of the SmartSurfaces course. The actual actuation is by a grid of servos powered externally and controlled through inputs from an Arduino Mega and the LDRs. The materials used in the assembly of the individual modules were 3/16" cast acrylic cut by laser and 3/16" 6061 aluminum sheet cut by water jet.

Simon
Simon is a heliotropic, feel-good machine. He interacts with a user through motion and LED color mixing and enters a default solar-tracking mode when not in use. Face recognition technology, a simple joint system, and a flexible LED array make possible a wide range of movement and interaction while photovoltaic panels provide the power. By fusing emotional connections with the user, we hope to transform the concept of sustainability from a condition of sacrifice to that of pleasure.

Exposure
Rather than using solar cells to convert sunlight into electrical energy, we are concerned with using the power of the sun in a more direct way. Exposure is a biological, heliotropic lighting system powered by photosynthesis. Living inside the piece are several Dinoflagellates, Pyrocystis fusiformis, aka bioluminescent algae. The bioluminescence of the organisms are set to a biological clock quite similar to our sleep cycle. During 12 hours of daylight Pyrocystis use the available light to photosynthesize, producing their own food and oxygen. At sunset the cells produce the chemicals that cause the luminescent reaction. If agitated during their 12-hour dark cycle, the algae give off a glowing blue light. In Exposure we have harvested several bioluminescent algae organisms, and embedded them into an architectural array. Within the array, varying panel heights correspond to the density of algae organisms contained in each unit. Infrared sensors located below the panels detect human presence, and trigger a motor. Attached to the motors, a cam makes contact with the panels creating enough motion to agitate the algae and expose their bioluminescent glow.

Smartsurfaces

University of Michigan's Smartsurfaces course offers a collaborative, project-based learning experience in which artists, designers, architects and engineers come together to build physical systems and structural surfaces that have the capability to adapt to information and environmental conditions.

The course will operate as a multidisciplinary, hands-on think-tank where participants will pool their knowledge and skill sets to work together to produce environmentally sound and socially responsible projects. Public exhibition of these funded projects will provide an opportunity for participants to present their work to a wider audience and to review their achievements.

Projects will make use of the resources available to all participating university units, such as:

parametric modeling
digital fabrication
networked sensors
microcontroller programming
energy harvesting

The course begins September 11, 2009.

Smartsurfaces (course)

"In order to prepare for a life of productive endeavor in the 21st century, undergraduates at the University of Michigan must learn problem solving across disciplines and launch inquiries in uncharted territories of knowledge and practice. They must examine the assumptions that inhere in a disciplinary perspective and integrate material outside of patterns they are taught. They must locate issues within larger frameworks of thought, negotiate multiple perspectives, and develop habits of critical questioning and creative problem solving. In addition, they must learn how to find their way through disconnected bodies of information and perspectives and create their own path to a coherent education. We believe that the major problems of our time, from the environment to poverty, from human rights to terrorism, from religious movements to health issues, cannot be studied effectively within any single discipline; all involve integrative, cross-disciplinary thinking."

Reading Material (books)

I've recently purchased a couple of books that I've been meaning to get for a while (too busy teaching/making stuff).

First up is the catalog from MoMA's Design and the Elastic Mind that features What's Cooking Grandma - the Human Beans project that we commissioned in 2006 for Perimeters, Boundaries and Borders. It is excellent. However, I was a little disappointed not to see Geoffrey Mann's piece Attracted to Light that was part of the MoMA exhibition (his Flight - Take Off was shown in PBB). I guess MoMA made up for this omission by acquiring the work (I'm quite proud of this, since I helped Geoff to make the Rhino file watertight).

No such oversight on the part of Troika. Their Digital by Design book is sumptious. (Also nice to see PBB mentioned in the section on Simon Blackmore).

This book is beautifully designed and well worth the investment. I'm now looking forward to the publication of the book from the inter_multi_trans_actions symposium (most of whom are included in Digital by Design). Julian Bleecker and I contributed a chapter to it.

Fire (project)

'Fire' from John Marshall on Vimeo.







The 'Fire' project is going well. It survived the rain. Apparently there is some will to make it permanent. There are some great photos of it on Earl Carlson's site.

Rhinoceros just simply rocks!

When I set up my files recently to CNC rout the plywood profiles for my latest project I made the newbie error of drawing the outside diameter of the holes I needed drilled rather than the center points (it makes sense after the fact but was counter-intuitive for someone more used to RP than CNC). Anyway, after manually drawing all the center points I asked the good folks at McNeel if there was a simpler way to bulk insert these points. Pascal Golay just sent me this Rhinoscript:

'*****************************
'*****************************

Option Explicit
Call Main()
Sub Main()
Dim aCircles
aCircles = Rhino.GetObjects("Select circles",4,True,True)
If Not isArray(aCircles) Then Exit Sub
Dim sCircle,aPt
Rhino.EnableRedraw(False)
For Each sCircle In aCircles
If Rhino.IsCircle(sCircle) Then
aPt = Rhino.CircleCenterPoint(sCircle)Rhino.AddPoint aPt
End If
Next
Rhino.EnableRedraw(True)
End Sub

'*****************************
'*****************************

It works a charm. Since I've recently been working with Processing and Arduino - I actually sort of understand it, too. I was inspired to put in the effort to get over the inevitable learning curve with Rhinoscripting when I saw THEVERYMANY - this just makes it all the more so. For all those (like me) that are intimidated by code, I think this is a significant move:

Grasshopper™ - a graphical algorithm editor tightly integrated with Rhino’s 3-D modeling tools. Unlike RhinoScript, Grasshopper requires no knowledge of programming or scripting, but still allows designers to build form generators — from the simple to the awe-inspiring.

It had to happen...

"Philippe Starck is on the hunt for young designers to appear in a future reality TV series. Starck is to front a forthcoming BBC series in which emerging designers compete for a six-month placement with the superstar product designer. The show’s format is likely to be a cross between The Apprentice and Big Brother..."

THEVERYMANY

It was great to meet Marc Fornes and Skylar Tibbits at the CPATH workshop. They gave a great presentation. An interesting point that was made was the use of constraints not only in the physical setting for built structures but also in the code used to generate them. It was amusing to hear that one of the constraints for some projects was fitting the structure into a few suitcases.

After the workshop I visited Philadelphia University to see Tesselion : Adaptive Quadrilateral Flat Panelization - "... a project by Skylar Tibbits which proposes a system of flat panel tessellation derived from complex surfaces to enable ease in constructability and a directly evolved spatial environment through lighting, programmatic adaptation and structural simplicity. Each panel’s uniqueness is afforded by the efficiency of digital fabrication while coded parametric relationships allow an emergent structural efficiency, from a single panel to the complete adaptability of the surface as a whole."

PBB Book (finally) Published

The 'Perimeters, Boundaries and Borders' publication (ISBN 978-0-652-355-2) is now available. You can buy a printed copy (for $18.95 US) or download it (full resolution, no cover, 80 MB) for free.

'Perimeters, Boundaries and Borders' was made possible through funding and support from Arts Council England, Manchester Institute for Research and Innovation in Art and Design (MIRIAD) and Lancaster City Council. 'Perimeters, Boundaries and Borders' was presented by Fast-uk in partnership with folly as part of the f.city festival of digital culture in 2006. The publication is supported by MIRIAD.

[N.B. If you were involved in the show I will be getting copies to you in the near future. If your contact details have changed please get in touch and let me know].

Algorithms and Scripting for Visual Art (event)

I have been invited to attend the workshop 'Algorithms and Scripting for Visual Art' at La Salle University, Philadelphia, PA on May 29 & 30, 2008. This is the first in a series of workshops sponsored by the National Science Foundation CPATH Program: Revitalizing Computer Science through the Science of Digital Media. This workshop will examine how algorithms and computer programming are used in the generation of visual art, graphic design, and creatively imagined architectural spaces. The participants will discuss how to direct curriculum and pedagogy in introductory computer science courses toward both traditional computer science majors and students interested in digital art or web-based graphic design. I'm particularly keen because Marc Fornes will be there. Marc is the founder of THEVERYMANY a design studio and collaborative research forum engaging the field of architecture via encoded and explicit processes. Marc is also a curator of scriptedbypurpose.

Design Connexity (event)

The Eighth International Conference of the European Academy of Design will take place at The Robert Gordon University, Aberdeen, Scotland, 1st, 2nd & 3rd April 2009.

Conference themes are:

Design Connexity
As the trend towards globalisation continues there is a growing connectedness between all our actions and a growing interdependence between the social, economic and the environmental. This increasing connectedness raises new moral and ethical issues and challenges. This concept has been termed ‘connexity’ (Mulgan, 1998) and provides the title for the conference and the backdrop for the themes of the EAD 08 Conference, which seeks to explore the implications of these trends for design research and practice.

Design Interconnections, Intersections and Convergence
This theme is concerned with the growing inter-connectedness of design, the interaction between design and other disciplines and the convergence between disciplines. Are design schools becoming the new business schools? Are new design professionals emerging that challenge the existing notions of what designers do? This theme invites papers that consider the impact of inter-connections between disciplines, the professions, and the implications for design education and professional practice.

Design Empathy
Products and environments need to satisfy functional as well as supra-functional needs (including the social, cultural, emotional, aspirational and spiritual). The data that can shape and guide decision-making can be visceral and ephemeral. More compassionate design approaches are necessary to ensure empathy and shared understandings are developed, and are particularly sensitive to how individuals communicate. We live in a verbo-centric culture, yet we experience the world visually. This theme invites papers that address issues, strategies and theories that consider empathic design.

Design Thinking
Design thinking is concerned with bringing about improvements in the human condition. This contrasts with critical thinking, which is concerned with the analysis and the breaking down of existing ideas. Design thinking is a creative process based around the building up of ideas. Design thinking does not seek to evaluate, as there can be no simply right or wrong answers. All ideas are welcome, since these have the potential to provide creative solutions. Design thinking offers strategies which can be applied to everyday situations. This theme invites papers that provide insights into the ways in which design thinking can be applied to address the critical issues facing contemporary society.

Service Design
Service design is concerned with both the tangible and intangible. It may be concerned with human interactions within systems, environments, communication and social interactions between people and organizations. It requires designers to question existing assumptions, undertake close observation of environments, provide diagnostic assessments and envisage new solutions. It has been applied in areas such as information services, health and education. This theme invites papers that provide insights into the application of service design that offer new solutions to tangible problems.

Design Boundaries
In a post-modern digital age we can witness attempts to combine art and technology crossing the boundaries in what was originally described by C.P. Snow (1959) as the ‘two cultures’. Snow’s fundamentally convergent position sought to expose the cultural divisions between art/humanities and science/technology. New design courses are being developed that embrace the concept of transdisciplinarity, moving beyond traditional subject boundaries. This theme invites papers that explore the boundaries between disciplines and professional practices, for example between design and architecture, design and craft or design and fine art.

Responsible Design
Designers are often cited as being major contributors to the ever-growing problem of waste as landfill sites fill up with discarded products that were designed without any consideration for recycling or reuse. Responsible designing makes it imperative that new products are designed with ‘cradle to cradle’ vision. This theme invites papers that explore the issue of responsible design, developing new strategies and insights into how this may be achieved.

Anti-Design
The Ad Busters web site states that: “We are a global network of artists, activists, writers, pranksters, students, educators and entrepreneurs who want to advance the new social activist movement of the information age. Our aim is to topple existing power structures and forge a major shift in the way we will live in the 21st century”. Is this the beginning of anti-design, a reaction against our material culture? This theme invites papers that challenge our notion of the role of design in the 21st century.

Digital Design Futures (exhibition)

Automake and Future Factories: Digital Design Futures is an exhibition that explores the significant role of digital design in the creation of contemporary craft and design.

Automake presents the work of Justin Marshall, a craftsperson/maker whose research investigates the integration of a range of digital technologies into ‘traditional’ art and craft practices, leading to the creation of innovative new work.

FutureFactories presents the work of Lionel Theodore Dean, who has acted as a consultant to the transport and interior products industry for twenty years. His research is based around the use of rapid prototyping for the mass individualisation of products.

The exhibition is at The Hub (national centre for craft & design) in Sleaford, Lincolnshire from 3 May - 8 June.
