Complete Galt Playplax 1983 Design Toy Set - Squares and RingsI had a set of these Galt Playplax pieces when I was a kid, and I swear not a week goes by that I dont think of them. As a child, there was something super magical about them, and I remember spending hours building with them, then peering through the kaleidoscopic towers of rings and squares I'd constructed, studying how the colors merged and the shadows they cast (I recommend using these on a white table!) Now that I have a set in hand some 40 years
