iPhysics is an app that was available for download to jailbroken iPhones, but it is coming to the App Store! Many different games and puzzles have been created for this physics engine app, including a pinball game, an aquarium game, and other unique games and puzzles that were created by different users of the app. I enjoyed playing the different games for this app, and it will be an excellent addition to the App Store! The developer's site is located here: http://www.iphone.r4m0n.net/?p=54 .
