The Spirograph!! I had one of these as a kid. When I saw the deal on Woot I had to get it for the boys. They were looking for something to do one morning so I brought it out. It was a huge hit. They spent the morning making Spirograph art and using the paint spinner. I love seeing them get so excited about little things. They continued to make more in the afternoon. Now we have quite a collection of circles hanging up around the house.
