Analog LED Clock

Wellyb00t has built a cool Analog LED Clock based on a PIC 16f877 microcontroller. Given the complexity of the hand wiring the spiderweb of connections on the back of the board is beautiful. You can see more pictures including the schematic here.

    I’d buy two, and hang them beside eachother; one backward so I can admire the wiring.

    I just love this!
