This mechanical kitchen timer combines a tape-measure and an egg-timer: the pull-out tape is marked with time increments instead of distance measurements. Pull it to the desired time and it slowly retracts into the timer-body, sounding a bell when it is fully retracted.

Update: Kurt sez, "you don't simply pull out the tape to the desired time. You pull it out ALL THE WAY and then use a dial on the bottom to retract the tape to the right time. Not as cool." I agree. How disappointing.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
