There have been several overly cruel alarm clocks pop up, the Sonic Boom alarm has been probably the worst, that is until now. This clock appears perfectly innocent, but it actually uses a bit of negative reinforcement to get your rear out of bed.
Every three minutes after it goes off, if you don't shut it off, it will make random phone calls from your cellphone. That's right, have a number you're hanging onto for sentimental reasons but would never call, it may get dialed.
Even worse is if you happen to wake up someone that wasn't ready to be awake yet. I'm fairly sure that this would be extremely effective to have you bolting to shut it off in time. This is still a concept design though, so the world is safe for the moment. It was created by Alice Wang.
