When our daughter was...oh...two years old, I picked up a Lite Brite at Goodwill for a quarter. It has pegs and those papers with the cool designs, and the lightbulb that came with it even works!
Recently, we have been using it as a fun little tool to learn some of the basic constellations. Just put a piece of black construction paper on the front, then add the shape of the desired constellation.
Turn off the lights, turn on the Lite Brite, and yippee! The little dipper!
Have fun learning,
