Are you the kind of guy who likes multimeters? Do you like clocks? Well have I got a deal for you. This multimeter clock is apparently easy to build if you understand CNC milling and electronics. It shows the time using retrograde dials that pop back to the beginning once they reach the end of their display values.
You have the full build log right here and you can make this thing look like whatever you want. I would make mine look like that robot from Pee Wee’s Playhouse.
