iPhy

There are many games out there using physics simulations, but have you ever seen one that allows you to play "freestyle"?

With iPhy, you can choose between different object types: static lines, circles, rectangles and freeform objects. By turning your device, you decide where the gravity goes. Place your iPhone or iPod Touch flat on the table to disable gravity, just like in deep space. But the most interesting features are the joints. You can choose between fixed or spring joints to connect objects together. To make the simulation even more interesting, nudge objects or give them rotational forces and build objects like driving cars!

To start, just choose the oject type and draw onto the screen and discover the power of the chipmunk physics simulation engine. Did you make a mistake? Double tap an object to delete. Start over? Triple tap to delete everything.
