Blinking LED

[forsakenrider]

Im looking for a simple circuit that would make a 4 colour LED, or a bunch of LEDs, go through their colours randomly or over and over in sequence when "ON". I searched and could really find anything since I dont really know what to call it. Any Ideas?

A few I found a while ago.

It would also be very simple to trigger a CD4013 decade counter with a 555, and have it count 1 thru 4 and reset, giving you a sweep of the colors in the LED.  Just mentioning it since that chip is ubiquitous...
