It seems to be magic when you see this clock hanging in the air with no support. But its the magnetic force which plays a major role. Just plug the base (which has to be bought alongwith the clock) and adjust the clock in between until there is a beep indicating the right place. The levitating clock uses the magnetic force to float an LCD clock inside a funny looking base. It also features an auto-rotate mechanism to spin objects clockwise, or counter-clockwise (as well as the clock you can buy an optional floating space shuttle). I think this is probably best used as a cool executive desk toy rather than an alarm clock, as I can imagine sleepy fingers moving the clock a bit too much when going for that snooze button (then again the crashing noise may really wake you up). It is available at Think Geek.
