BMW has released a Z4 Roadster game for the iPhone a couple of hours ago.
Check out the video on YouTube:
This is part of BMW Z4´s "An Expression of Joy" campaign. Players will be able to explore, customize, create and virtually drive the virtual Z4 . Players may "draw" using the wheels of their car by choosing different colours so that their tyre tracks create marks as if creating brushstrokes on a canvas.
The game is available for iPhone & iPod Touch and can be downloaded for free from the iTunes store.
