How would I go about building a LED randomizer. Purpose... Well, imagine a war ship in space with holes in it and fires raging in the holes and spaces as the damage control parties try to bring the ship back from the brink. Remember the pilot to the new Battlestar Galactica when she got hammers and Ty had to vent the spaces on fire to save the ship? I don't want to vent the ship. With a series of red yellow and white LEDs attached to a randomizer, you could make fires seem to appear. I am told it's simple... so yeah. How simple is it?
