Griffin Technology - PowerMate

You can program this little jewel to do anything your keyboard can do. Everything from being a supercool volume knob, to scrubbing through and editing audio and video. And the manufacturing is incredible. Not only can it be turned, but you can push down on the top like a button. I've slammed my hand on it in frustration, and it took it beautifully. It scrolls like a knob on a high end stereo system. I love this gadget.
