What is the "closed" circuit for red then green led, on/off? Answered

hi for a project i am doing, i wanted to make a 3d led cube but it was to simple. BUT i can do it if i can make it with different led turning on and/or a pattern. So my question is.. what is the schematic for a multi led 3d cube? So that when i turn it on it goes red then when i turn it off it turns off but when i turn it on again it goes to green or a different colour? Also, if you have any other ideas of making a more "advance" version of a 3d led cube plz post here as well :D

Look up charlieplexing http://en.wikipedia.org/wiki/Charlieplexing it will give you a start. Much depends on your microprocessor skills..

http://www.picaxeforum.co.uk/ is another place to look as they have covered charlieplexing many leds from microprocessors in the past.

Comment to TheWelfareWarrior - ask him if he's figured-out how it works. Might be your easiest option.
