Silly CSS Fun for a Sunday Afternoon

Yesterday, I decided to mess around with 3D CSS transforms. I've used them here and there for various things (the flip animations in, for example) but nothing silly.

My mind wandered back to an early HTML5 canvas demo I saw ages ago where Jacob Seidelin had written Super Mario Kart in JS and I wondered if it would be possible to do the pixel-pushing part of that demo in CSS.

An hour later and we have this:

Super Mario Kart CSS

Yes, it's silly. Yes, it's nothing like playing Mario Kart and, no, there isn't any acceleration. That wasn't the point, however. View the source to see the description of the rotations and transforms.
