The Digi Alarm clock is an alarm clock with no off button, when the alarm goes off, you have to lift the sphere out of the middle of the alarm clock and place it back to turn the alarm off.

The idea is that by lifting the sphere you are going to wake up, it certainly seems like a good idea, when my alarms go off in the morning I just hit the various snooze buttons, which I can now do in my sleep, so this might actually get me out of bed.
