Seven Experiments in
Procedural Animation

Karl Sims, 2018


This one-hour piece of slowly moving digital textures and patterns was commissioned by Boston Cyberarts for Boston Properties' new 35-foot video wall in the courtyard of The Exchange at 100 Federal Street in Boston.

The animation was created directly from custom computer code that employs various fractal algorithms, procedural noise, and reaction-diffusion techniques. While the moving images are purely defined by mathematics, they still manage to evoke a biological aesthetic by resembling sea creatures, neurons, or other microscopic structures that transform from one emergent pattern to another.

For additional technical information, visit these tutorial pages about Julia set fractals and reaction-diffusion simulations.

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.
