A chaotic musical instrument for iOS. Catalyst will change the way you think about your iDevice.
Record your voice, your surroundings, or even your favorite songs onto Beatballs that play whenever they hit the edges of your device. Fling them at (near) light-speed, at a tortoise's pace, or to the rhythm of your favorite song to create personalized, infinitely-long compositions. Change the speed coefficients and decelerations of the balls, or the individual sizes, to make ridiculous tracks that you'll want to play for hours.
Emulate your favorite video game, create a symphony, or even put together live mash-ups of pop songs. The stage is set— are you ready to pick up the baton?
