Growing Objects (8 new items)

Our solo exhibition "Growing Objects" explored natural growth processes through simulation and 3D printed sculpture. It was hosted by the Simons Center for Geometry and Physics in Stonybrook, NY in August and September of 2014. Our work at Nervous System explores processes which cause structure and pattern to emerge in nature. We adapt the logic of these processes into computational tools; translating scientific theories and models of pattern formation into algorithms for design. The exhibit focused on four such computational systems: reaction (2010), xylem / hyphae (2011), laplacian (2011), and florescence (2014). These algorithmic investigations of nature were each documented by digitally fabricated sculptures and a series of posters explaining the math, science and natural inspiration behind them. Each growth process was also illustrated through 3D-printed zoetropes. When in motion, these kinetic sculptures animate the formation of complex forms and when still they allow the viewer to examine each steps of the growth process. While inspired by natural systems, these sculptures do not directly mimic specific phenomena but are instead open-ended explorations of the mathematics and logic behind them. The generated forms propose a new way of thinking about how we can design or "grow" our environment.

Reaction system + videos (5 new items)

We wrote a computer program to generate 3D forms using a mathematical simulation of Reaction-diffusion, and used this software to grow the designs of the reaction collection. Parameters of the simulation can be varied for differing effects, creating different types or directions of pattern. These parameters are controlled and change through space to express design intent. The process begins on an imported underlying surface, and a 3-dimensional object is formed by embossing or removing material from that surface based on the chemical concentration present at each point in space. Multiple scales of pattern and simulation are used to create more detailed forms.

Inspiration

Reaction-diffusion (RD) is a canonical example of complex behavior that emerges from a simple set of rules. RD models a set of substances that are diffusing, or spreading; these substances also react with one another to create new substances. This simple idea has been suggested as a model for a diverse set of biological phenomena. All kinds of animals from fish to zebras display interesting color patterns on their skin and shells which play important roles in their behavior. However, the underlying cause of these patterns is still not understood. In 1952, Alan Turing suggested the RD system as an answer to not only this question but also the more general one of why cells differentiate. How do individual cells locate themselves in the larger scale structure and pattern of an organism? The patterns seen on the animals occur over a scale much larger than a cell, yet they display remarkable self-similarity on every part of the animal’s body.

Turing studied the behavior of a complex system in which two substances interact with each other and diffuse at different rates. He proved mathematically that such a system can form stable periodic patterns even from uniform starting conditions. One of the most interesting things about RD is that you can have a homogeneous system where every cell is doing exactly the same action (for instance just producing a certain amount of some chemicals); but from this one process a large scale structure emerges.

SIMULATING REACTION-DIFFUSION

One of the intriguing aspects of reaction-diffusion is how a simple chemical system can produce a variety of patterns through small changes. Nervous System’s reaction diffusion experiments use the Gray-Scott model. This describes a system of two chemicals, often referred to as U and V, where U and V combine in a reaction to form more of V. Additionally, chemical U is produced at a certain rate, while chemical V naturally decays at a fixed rate. Changing just these rates of production and decay results in patterns of dots, lines, holes, or spirals. By working with multiple scales, varying parameters, and using anisotropic diffusion (in which chemicals flow more easily in one direction than another), it is possible to sculpt reaction-diffusion patterns.

Hive Trivets

We designed the Hive Trivets with our Radiolaria software in 2010 for tableware brand Modern Twist. -- A modular silicone rubber trivet featuring an organic embossed pattern inspired by cellular forms. The Hive trivets fit together to create a functional space that is also pleasing to the eye. They come in an array of fun colors. Use them individually for hot plates and pans, piece them together for larger dishes and pots, or make a honeycomb-esque table runner. Created in collaboration with Modern Twist, these clever kitchen + dining accessories are durable flexible and soft to the touch. The trivets are made of FDA approved food-grade silicone, heat resilient to 675 degrees and are skid and slip resistant; making it ideal for every surface.
