I konw the ipod touch has this, so here it is. A game where you always go straight and you have to dodge the cubes. You could use touch support to move left and right and up and down for speed boosts and slowing down. It could be in landscape view.
Here is the link to the flash game-http://js.pp.sohu.com/ppp/blog/widgets_0914/game/3dcube.swf
