Ever dreamed of being the all mighty ruler of a tiny desktop world? The EcoSphere ($80-$490) will let you live out this crazy little fantasy of yours. It's the first totally enclosed and self-sustaining ecosystem. The glass globe is filled with filtered sea water, red shrimp and algae. You never have to add food or water, and just have to provide indirect natural or artificial light. EcoSpheres have an average life expectancy of two years, so be sure to tell the tiny shrimp to live it up and have drunk sex with other random shrimp as much as possible as their armageddon approaches.
