Race in a random landscape with three cars that are controlled with the accelerometer. Change cars by double tapping on the screen. Change of view and engine force is done in preferences. It is possible to change between a set of default ground plates, sky domes, as well as controlling the fog color used as either default gray, fixed color, clock colors, or random clock colors. It also exists some cylinders and cubes to collide with.
The landscape is rendered using OpengGL ES 1.1 combined with some physics and collisions.
To unlock all features you need to purchase a license key in the live wallpaper settings, its the normal Google Play In-app purchase flow.
