Sort of off the subject...
I bought an item at Sharper Image years ago, it was a game, where you got a bunch of metal poles about an 1/8" in diameter, some plastic couplings, and about 500' of plastic tube, also about 1/8" in diameter. The idea was to build a roller kind of assembly with it. It was pretty slick, you could add loops, hills, whatever.
The point is that I've never found another one of these games, and I was wondering if anyone else knew what I was talking about, or where I could find one. I've never seen them again, and last time I was in San Diego (where I purchased the original) the store had closed up.
Any help on this would be greatly appreciated!
Thx
