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.
Original software was used 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.
Attempts were made to bring together several concepts: chaos, complexity, evolution, self propagating entities, and the nature of life itself. This botanical form of life, reproducing itself from planet to planet through space, is in many ways analogous to other self replicating systems including organisms, entire species, or even ideas. A window into this system, replicating on a grander scale, is meant to increase awareness of self propagating systems in general, as well as inspire thoughts about our entire planet of life as a whole entity.
