This is really cool. I'm also reminded of a game on SGIs called Mekton. Mekton was originally a mecha-combat RPG designed by Mike Pondsmith, the creator of Cyberpunk (2040, etc.); it was made into a multiplayer video game using OpenGL that was set on a ring-shaped space colony. When you land, you can see the landscape curve upwards ahead of you, as you're on the inside of the ring.
