EcoSphere
While browsing through ThinkGeek I found another amazing “gadget”. I think this is even more interesting than the ant farm. A self sustaining ecosystem! You’ll find two forms of active micro-organisms (bright red shrimp and algae) existing in a clear “soup” of filtered sea water. No need to feed or clean either, just give them light. Or instead of spending US$80-180 on one of these, you can get a ‘Paula Hayes Terrarium‘ for US$10,000. :/
