Shaky

shaky turns the iPhone into a hand-exercise device. The user shakes the phone in a prescribed pattern (back-and-forth, circle, oval, figure-8). Each rep throws a 3D basketball, and how well the rep matched decides where it goes: - **Too hard** flies over the hoop; **too soft** falls short. - **Wrong path** misses to the side. The side follows the sign of the main error. - **Wrong tempo** gets coached ("Faster!") and nothing is thrown.
