Looks like our cool clocks section will fill up quite quickly with the second entry this week being a levitating clock from Think Geek.
The levitating clock uses the 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).
