Ridiculous laser wall clock

[nickjohnson] has produced an incredibly silly laser wall clock. It was built to test out his PWM servo controller board. He created a wall poster featuring numbers 0-9, hour, minute, AM, PM. The controller points at each symbol in sequence to spell out the time. It changes position every second which creates a nice ticking sound. The clock may be goofy, but you should have a look at his parallel port controller since it’s designed to be simple and uses common components.
haha. i like how it spells out the time
