this app, uzu, looks sick. by it’s own description: “technically speaking, Uzu is a kinetic multitouch particle visualizer.” basically it lets you do awesome things with billions of lil light particles on your ipad. and it responds differently to being touched with one finger, two fingers, etc.
the author has a great line right when he get’s to the part about what you can do when putting more than five-fingers on the ipad:
past five fingers i recommend, of course, using two hands. um most of you – of course – have no choice.
i was exploring this after reading an article about edge gestures, and how apple bogarted a bunch of the best gestures, and not only that, but they’ve also made them usable inside the ‘canvas’ thereby limiting the flexibility of apps.
