"DLA Painting #6638"

Digital print, 5" X 5", 2006.

Diffusion Limited Aggregation (DLA) paintings are visualizations of topological structures that are formed, starting from "seeds", by particles undergoing Brownian motion colliding and adhering to them. DLA paintings in this series were made by locally constraining the random walks of the individual particles (here realized as paint particles). The interplay between randomness and symmetry is achieved by compositing ten different layers each consisting of three such structures.

"My recent computer generated algorithmic art works have been based on visualizations of simulations inspired by mathematcal models of natural processes. Examples include cell morphogenesis, swarm behavior, and diffusion limited aggregation. By controlling various drawing attributes and by making use of image compositing techniques I try to direct the viewer's attention to the intricacy and complexity underlying such processes."
