OSC Physics is a control surface that emulates real physics. It supports sending OSC messages over a Wi-Fi network. The app reacts to the orientation of the device taking advantage of the iPad's accelerometer. It sends X/Y coordinates, angular velocity, collisions of every object on stage. Great for controlling synthesizers, sound design and more. It works with any software capable of receiving OSC messages: Pure Data, Max/MSP, Logic Pro/Express, Supercollider and more.
