If you've ever fiddled with electronics, then you'll recognize the photo above as resembling the classic Simpsons 260 multimeter. But rather than measuring currents, the oversized device is actually a clock!
Alan Parekh of Hacked Gadgets created this awesome clock that keeps time and outputs a calculated current to each meter to display the "current" time (get it?).
Check it out (with video clip of the clock in action): Link - Thanks Alan!
