Seven Experiments in
Procedural Animation

Karl Sims, 2018

These 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.

A 5-minute version of this piece was exhibited at ARS Electronica in the Deep Space 8K Theater and the 2019 Animation Festival in Linz Austria. The original one-hour version was commissioned by Boston Cyberarts for the 35-foot video wall in the courtyard of The Exchange at 100 Federal Street in Boston.

See these similar still images of fractals, reaction-diffusion and evolved noise textures, some of which these animations were based on.

Here is also an old technical paper from 1993 about interactive evolution of equations for procedural models, and a Genetic Images interactive art exhibit that allowed visitors to perform this process.
