OrigAudio has posted a video (http://www.origaudio.com/) on the Rock-It, an US$49.99 vibration speaker system.

The Rock-It works with iPods, iPhones, laptops and more. It takes music from the device and generates it into vibration sequences. It sends those vibrations through the Rock-It “pod,” which you can stick to any object.

The Rock-It requires two AAA batteries (not included) or an USB connection. It comes with an USB cable and four replacement sticky pads.
