A timely display for romantics and werewolves!

There is something very inspiring (and in the true spirit of experimentation and science) about making a device to better understand the universe around us. Described here is a simple clock consisting of 12 light emitting diodes arranged in a circle, which turn on individually to indicate the current phase of the moon, new, full, waxing and waning.

The circuit is based around a PIC-microcontroller. It is easy to build and is suitable for construction by beginners.
