This circuit can be made to produce interesting and attractive light effects using just a cluster of red LEDs and one of green LEDs. One effect is first alternating between red and green, and then lighting red and green together. With the exception of the triple LED devices (Rapid Electronics # 56-0205 for green, # 56-0200 for red) all parts are cheap and easy to find, possibly even in your junkbox.
