PUBLIC MARKS with tag watch

An array of LEDs randomly changes patterns every 10 seconds or so. To read the time, simply count the number of dots per digit. The main pic shows the time, 22:11. Different colours are assigned to different digits, red-10hours, amber-hours, green-10minutes, blue-minutes. Using 3mm superbrights means the clock can be read daytime or night (though it'd be washed out in full sunlight). Having a random pattern is a lot less distracting than having numeric digits staring at you...this would also be a great project for adding to the front or size panels of a PC mod
