Totally love it!

Still I would like to see this used in a game. Procedural asteroids is something I could really use for my project atm. Or a procedural world, maybe with less detail. Or a procedural mountain with caves in it...

Of course, I have no idea about this stuff, so I don't know if any of the above is realistic.
Are you going to make a game with it? or are you just messing around for fun atm?

Great progress, the lod-steps seem to work real nice...
