Clever designs: Top ten alarm clocks
From uberreview The top ten alarm clocks. They rank them by annoyance, but from my perspective these are all clever in some way. Some work better as concepts I’m sure, but they deserve points nonetheless.
A perenial interview question at Microsoft was “design an alarm clock for one of: the blind, the deaf, the stupid, the hungover, the heavy sleeper, or the paranoid.” Many good answers can be found in this review.
The twist (beyond combining constraints, such as stupid and hungover”) was always that the clock had to cost less than $10, but sadly all of the ones listed here are well out of that price range.
