Artificial Life (AL), a mobile game and app maker, has just released the final version of its BMW Z4 Experience app for the iPhone and iPod touch. Normally I'm not one to laud apps made to advertise ridiculously expensive luxury cars, but AL has packed some pretty rad features into this app.

This BMW marketing ploy consists of four different mini-games. One of them is a standard driving game with fairly decent graphics. You can only drive the BMW Z4 Roadster, of course, but it still looks kinda fun. There's also a "traveling salesman style" game that looks like a navigation-based puzzle game. Both of those mini-games are pretty run of the mill; it's the last two that are really cool.

The "BMW Z4 Experience" comes with an 'art experience' mode, and a 'free driving' mode. In the first, players can make splatter art paintings by driving their Z4 through a paint-filled canvas. In the free driving mode, players use their tires as a paintbrush to create their works of digital art. When they're done, players can upload their artwork directly to Facebook Connect and show their friends.

Both of those art modes show a remarkable amount of creative thinking for what is essentially a transparent advertisement for Beemers. The app costs .99 cents, which sounds like a fair price for what is essentially a cool new doodling tool.
