Commercial time:

There's a kit, sold by Jaycar, that's a five pointed star made up
of 30 leds, driven by a 20 pin 8051 derived 89C2051 micro. The leds
flash in nifty patterns, like rotation of various bits in both
directions, flashing, buildup and down from the centre out and in,
and a rotation of running lights bouncing around the perimeter. It
repeats after about a minute. Very fetching. About 4 inches across,
uses normal red leds.

Needs a 150mA dc supply with enough volts to drive a 7805 reg, so 9
volts is ok as is. 12 volts would need a heatsink for the 7805.
