Panspermia is the name for the theory that life exists and is distributed throughout the universe in the form of germs or spores. This piece places the viewer in the middle of a virtual world of an aggressively reproducing inter-galactic life form, and depicts a single life cycle of this unusual self propagating system.
Karl Sims used an original software to create and animate forests of 3D plant structures. Artificial evolution techniques were used to interactively select from random mutations of plant shapes until a variety of interesting structures emerged. The subject matter of the piece suggests the underlying biological methods that were used to efficiently create an unusual level of complexity. Dynamic simulations and particle systems were also employed to achieve motions that are calculated automatically.
