A simply wonderful idea that gave me a wide smile. I'd really love to see more applications like this.
Would be awesome to be able to scale the car so I can see it better, and to change its colors. Maybe even little items on the screen for the player to collect.
If it weren't for the educational label at the bottom right that obscures my clock, I'd probably have this application on 24/7. It's just that great. Please make more.
