I used to love Lite-Brite. It has changed since I was a kidlet, but it's still available. I used to make my own outer space images (like the ones you'll see in the video below), and I even used it one Halloween to complete my Darth Vader costume. I took an empty golf ball box, painted it black and put a flashlight in it, then stuck a bunch of Lite-Brites in to simulate the neat computer box button thingy on his chest. Darth Vader is so cool! I digress... watch this cool Lite-Brite stop motion video:
