Yanko Design has an interesting concept for an alarm clock. While I’ve seen countless variations of clocks set to wake you up (the one that rolls away from you is my favorite), this is one of the more ingenious ones. This clock, designed by Johan Brengesjo, revolves around the idea of waking you silently. The clock itself is just like any other, the way it wakes you however is what makes it so damn awesome. The sleeper slips on a rubber based bracelet that vibrates to wake you up. It’s no Wake ‘n’ Bacon, but definitely cool.
