Ok, this would be a cool application for iPhones, Pocket PC and the like — a dialer which presents an old style rotary phone dial, and you have to put your finger in it and spin it around the center, and then it slowly twists back and plays the sound of a dial returning. A bit like how you control an iPod, but slower.
Completely useless, other than for having fun and explaining to kids why we call it “dialing” a phone.
Perhaps with the iPhone accelerometer you could actually spin the physical iPhone to move the dial. No way to generate the classic sore index finger and physical resistance though.
(Some people made jokes about rotary dial on the iPhone before it was launched but I don’t know of anybody who actually did this.)
