Has anyone checked out Adobe Atmosphere? It lets you create online 3D worlds, and it its current Beta stage its free. Its really really sweet, but probly one of the most complicated Adobe programs to use... I am still playing with it.
How far along have they come with it? It seemed very odd when I was messing around with it when they first put it up. Friend of mine was working on an atmosphere for it i'm going to go ask him how that whent.
