These seven animated textures and patterns were created from custom computer code employing various fractal algorithms, procedural noise, and reaction-diffusion techniques. The moving images are purely defined by mathematics, but are meant to evoke a biological aesthetic by resembling sea creatures, neurons, or other microscopic structures that transform from one emergent pattern to another. An original one-hour version of this animation was commissioned by Boston Cyberarts.Karl Sims is a digital media artist and visual effects software developer.
