Presenting the single most amazing screensaver in the whole world: Electric Sheep. This damn thing is so amazing that you might even stop working and just wait for it to start ;-). Opensource and available for all major platforms. For the more techie people: it is a distributed screensaver that uses this distributed computer power to compute beautiful morphing abstract animations (known as sheep). The thing is even more interesting because evolution is involved: only the best (people vote for it) sheep "reproduce" to form better effect in order to please the audience.

Well before somebody gets too excited ... there are a few requitements: hight-bandwidth Internet connection and a modern computer are not so rare comodities nowadays so that will probably not be a problem.
