Cool hack (was Busses vs no busses)

I have a clock that works basically like this. The LED is mounted on
a spring loaded arm sticking up out of the base. You pull the arm to
one side, and release it. The time shows up floating in the arm.

It's pretty annoying to have to flip the arm to find out what time
it is...
