We are waiting on the Doom3 editor to come out. He has been working with Bryce to try and model that theme in a 3d world. He really wants to create some killer doom3/UT2K4 maps. Another friend of ours is working on the programming side, while Tim wants to create the themes, overlays, textures, etc.
We aren't quite there yet, but I have been thinking about trying to get some kind of grant to get some better rendering equipment. Tim only has a 1.2Ghz machine, and when he wants to render something in Bryce, it takes about 15 minutes. I've been thinking about getting a 2.4Ghz Athlon XP board with 1GB ram and hooking it up as a rendering board.
We'd like to get a green screen and some motion capture devices so we could do real time 3d modeling....
