Progress...

Work is progressing smoothly, but is going to be interrupted by my laptop needing repair. However, so far:

- The menu system is working, and while it needs some more zest it works for now.

- Physics is fully working - ODE is integrated and working well, and quite a few cubes have been bounced around the track and smashed out of piles, etc.

- Collision detection works great - the game currently collides every single polygon on the track, which runs surprisingly fast. I'll move to separate collision meshes at some point, though.

- Cars work, although the suspension still needs a little tweaking, and the steering is far too responsive, and works when you're not moving. Downforce and everything exists, I've been happily driving on ceilings for a while.

So, at the moment, there are a few test tracks where the car goes round bends, round loop-the-loops, and drives on ceilings.

The next stages:
- A much better camera. The current one is fixed to the car and doesn't flip based on which surface the car is driving on.

- Weapons. Obviously.

- Some way to detect how far cars are along the track and thus how many laps.

I'll put a few screenshots of the current code up.
