welcome to my asteroid field

 So, as a short term goal for this project, I've decided to work on a 3D asteroids clone:

This is in 3D!  So what does this do at the moment:

• 6-DOF 'spaceship ' camera control
• Each asteroid geometry is randomly generated  [(although I reuse the same texture :(  ]
• Each asteroid moves with a constant intertia, and rotates, independently of each other
• Background starfield is randomly generated.  Stars are infinitely far away.

Limitations:

• Asteroids are drawn without lighting at the moment.  (There's no 'sun' present yet)
• Can't shoot
• Asteroids don't do anything when they hit each other (yet)

How am I generating an asteroid?  I'm starting with a cube, and randomly moving vertices around.
