The iPhone's accelerometer has been the cause for a lot of unique games that are hard categorize, Graviton is one of them. The basics: you control a ship where, with your accelerometer, you pick up "energy spheres" and try to progress to the end of the level. Simple enough. What makes the game interesting are the different obstacles: gravitational disturbances, lava, walls (oh believe me, I ran into enough of these for them to be considered obstacles), etc."
