If you have multiple iPhones lying around, this is a fun little diversion.
Here’s a video I made of my wife playing a board made of 6 iPhones: one 4S, two 4s, one 3GS, and two 3Gs. (I would have included my original iPhone, but Ultimate Shuffleboard requires iOS 4.)
The animation flickers and stutters with the two iPhone 3Gs in the middle, but otherwise, it works great.
For single-device shuffleboard, I recommend this Shufflepuck app.
And if you don’t know what shuffleboard/shufflepuck is (which is it?), spend some time in Pennsylvania.
