Solipsis - a Decentralized Open-Source MMORPG
Anonymous Reader writes "Calling it an MMORPG is a bit of a misnomer because at this point there aren't any players, much less hit points, monsters, or flaming swords. Solipsis is an open-source project that aims to create a decentralized multi-user virtual world. It's still very much in its infancy, and as such the visuals are a bit lacking, but the aim is to create an endlessly scalable user-contributed world and it seems it's a nice platform to play with."
Also vaguely interesting and along similar lines is Alan Kay's Croquet project.
It's not particularly mind blowing, but it has potential.
There are no trails. There are no trees out here.
