There are much newer, fancier versions available and we've put one on our Christmas list this year (hint, hint, Granna). I found the picture on a "toys of the 80s" page and I think I got ours at a garage sale for 3 bucks. The only issue is the choking hazard (uses marbles) but kids of all ages have been interested in it and it's a great lesson in teamwork, problem solving, and creativity. Marbleworks -- it works for me.
Head on back over to ROCKS IN MY DRYER for oodles of ideas!
