There's a link in the left hand bar to Adobe Atmosphere.

Adobe are in the process of developing a new 3D environment creation program by the name of 'Atmosphere'. Right now, the Beta software is free to download and Adobe are listening carefully to all the people using it. I'm one of them and if you're into this sort of graphics, its fascinating. People create "worlds" that others, on the other side of the real world can walk around and meet and chat in. There are some extremely talented "World Builders" out there, too and there are already hundreds of worlds to visit and explore. There's also a Forum for users, where there's plenty of help and advice available. Check it out if you're into that sort of thing. Click here.
