tyrant

Crave has seen all manner of sadistic alarm clocks, from models that emit sonic booms and electrical shocks to those that fly and roll away. But the appropriately named "Tyrant" from Taiwanese designer Alice Wang takes sleep disruption to a disturbing new level.

If you don't turn it off, this little monster will randomly dial numbers programmed in your mobile phone every three minutes, according to SlashGear. That's right--not calls to yourself, but to others who surely won't be amused. Mercifully, this is only a concept so far (we hope).
