True Alternate Worlds

I came across a very interesting read today. Laukosargas Svarog has used the framework provided by Linden labs’ Second Life and built what appears to be a true ecosystem. She has weather, birth and death of plants, animal polination. It’s a testament both to the flexibility that Linden has built in to their system, as well as the creative imaginations of a single individual. I wonder what would happen if her virtual plants were allowed to ‘escape’ her garden and colonize the entire world…?
