I had one about 50 years ago. Lots of fun and very educational. A lot of geometry and trigonometry can be developed here. You can even push a little pre-calculus from it. Mine set was long gone before I entered engineering but I'm sure some useful ideas were created/developed with it. I'm going to give it a few "trial rounds" and then it will become a Christmas gift. (Since it was already open who will know?) One of the ultimate in educational toys!
