Art feature for 2008: electric sheep.
Scott Draves · PubMed · 2008
The cover designs are still images from the Electric Sheep, a distributed screen-saver that harnesses idle computers into a render farm with the purpose of animating and evolving artificial life-forms. The votes of the audience of 50,000 users form the basis for the fitness function for a genetic algorithm on a space of abstract animations, each known as a "sheep". Users also may design sheep by hand for inclusion in the gene pool, so crowd-sourcing, or intelligent design, collaborates and competes with evolution. The images were drawn with the Fractal Flame algorithm, a generalization and refinement of Iterated Function Systems. Essentially the images are interference patterns between groups of nonlinear geometric transformations of the plane. The hundreds of floating-point parameters of these transformations comprise the genome of each sheep. This nonlinear map from genome to image defines a visual language, whose search and incantation brings the machine to life.
