Its a little rough-looking since it is hard to put polish on something when you don't really have a framework to work with. I have a bunch of screenshots up on my blog:

Procedural bits. Well, the tunnel system. It has a nice recursive tunnel system. When you reach the end, it calculates the next tunnel and moves on from there. And it remembers the state so if you go 10 tunnels forward, then go back, you'll find the tunnel you would expect there to be.
This ship itself doesn't look so hot, I'm hoping to fix that this week.
And maybe some sounds, but right now, its what I'm calling a minimal game. Oh, technology: C#, Tao.*, BooGame, OpenGL, and SDL. And it works on Linux.
