"Many of my computer generated algorithmic artworks are based on visualizations that arise from simulating mathematical models of natural processes. Examples include cell morphogenesis, reaction-diffusion and swarm behavior. Other works attempt to realize mathematical concepts. I try to focus the viewer's attention on the complexity underlying the computational processes."

This algorithmic design is made by instructing 6000 pick-up, carry, and drop mobile automata to collect virtual grains of color uniformly distributed in their environment and deposit them on polar curves of the form r^2 = a^2 cos^2(theta) + b^2 sin^2(theta). There are twelve such curves and each is assigned a different color.

This algorithmic design is made by instructing 6000 pick-up, carry, and drop mobile automata to collect virtual grains of color uniformly distributed n their environment and deposit them on ellipses. There are twelve ellipses and each is assigned a different color.
