I've always wanted to make an iphone platformer (I'm not stating it will for sure be on iOS, but it might be) where there's pixels and real life photos mixed together. So I'd snap good photos of things that could be used as part of a level. You are tiny made out of pixels, the enemies are, etc. The story is you get sucked into a portal which leads you to earth. The twist is that a scientest lends you a device, letting you turn certain objects into pixels, these objects will have an effect on the gameplay (for example, giant snake attacking you. you see a trash can blocking the way. Use your gun on it. Keep holding your gun down and using magic, it will follow your finger until you drop it on the snakes head, leaving the snake dead, saving your life.)
