I had some fun generating fractals with a program I just found called Chatoica. Take a look for yourself and let me see what creations you made!
Artistic Asides: Fractal Art
Proof of Concept: Chemical Reaction-Diffusion Systems
First Proof of Concept - Belousov–Zhabotinsky
I'm interested in novel ways to create and interact with visuals. Nature produces an astonishing array of designs and patterns. We hope to explore the possibilities of incorporating real-world phenomena as sources of Motion Graphics. I've been working with some Chemical Reaction-Diffusion Systems recently. I found a Auto-catalytic Self-oscillating 'chemical clock' known as the Belousov–Zhabotinsky reaction which ended up making some interesting patterns.
First in a series of investigations into using reaction-diffusion systems as seeds for live event visuals.
Aww look, its trying to express itself artistically. - Arduino ArtBot v0.1b
Arduino is an amazing microcontroller platform.  Bridging the gap between software development and interacting with the physical world is really amazing.  Jordan Sitkin and I made a very silly autonomous artbot. 
Planning to ruggedize it a little add a springloaded stick of chalk to it and send it out into the streets!
