Uzu bills itself as a “kinetic multitouch particule visualizer” which translates into really fun frickin’ fun interactive light show. By touching it with your hands you can freeze, move, contort, and change an explosion of multicolored lights through up to 10 points of contact. It doesn’t serve any practical purpose, but it’s probably the neatest app in the iTunes store right now that any iPad owner will use to show off the device’s “cool” factor.
From Uzumotion:
Points of light will shoot across the screen and fly to your command, twirling in a vortex of color and motion. Freeze and move Uzu in 3d space while contorting spirographic curves with your fingers. Uzu lets you quickly switch between 10 different modes of real-time animation by simply changing the number of touches you’re using. You can spend countless hours discovering the many unique ways of playing and interacting with Uzu.
Uzu is very happy when multiple people touch it. Uzu loves parties, children, music, cats, and pubs – although not necessarily in that order. Uzu has many plans for the future, but Uzu would like to hang out with you now if that’s cool.
It’s easier to see it in action than to describe it, so here’s a video from the creator. Althought it’s for the iPhone OS, right now it’s only available on the iPad in the iTunes store and is currently free for the July 4th weekend.
