"Spirograph" @MathPlayground

Is there anybody else out there that remembers spirograph? It was a favorite of mine when I was little. I found a game today at the MATH PLAYGROUND that is similar, called ART WITH SPIROMATH. It is so much fun, and my 2nd and 3rd graders had a great time with it today. There are some really fun games at the Math Playground - I have had this up for 2nd - 6th grades this week and they have loved the games here. It really kept them engaged!  Do you have any great sites that your kids just love? Leave a comment and let me know.
