Many people have the habit of fidgeting and the Denis Kalinin Rotator exploits this constant compulsion. The handheld mp3 music player has been designed with a simple and slim form, complete with a ring hole for the listener's finger.

The beauty of the Denis Kalinin Rotator is precisely the way the user interacts with the device. To adjust the volume, change the track or even charge up the gadget, one needs only to twirl the electronic around his fiddling digit.
