I had the idea for this after watching an episode of Stargate Universe. I really like the effect they have of the.. I'll just call it space wash, that flows over the ships force field. It reminded me of the cloud vapor that flows over an airplane. So my brain got working on how I could achieve such an effect, but first I needed something for the effect to flow over. I decided I'd go with a mixture of an asteroid and comet.
I was in the mood to play around with a Charger model that I built a while ago. I rigged it up so that the steering wheel had proper locking rotation of the front wheels, and so that when you moved the main controller back and forth the wheels would spin appropriately. There's also a control to disable the auto-roll of the wheels for animating brake locks and such.
