My friend Don Witte, the W in W.H.O., a construction kit toy company of the 1960s, designed several clever construction kits. In its day, his company was much in the same spirit as Modular Robotics is today. He wrote, “While adults are going to the moon, their children are playing with primitive wooden blocks, sticks, and nuts and bolts. Isn’t it time to provide our children with construction toys which fully utilize the advances in technology and the materials of the time?” We couldn’t agree more. The company produced working prototypes of four kits: Moduflex, Cylispheres, Zox, and MollyCools. They’re each different–Moduflex was perhaps the most technically sophisticated with gears and chains as well as a snap-together panel system, and it came in variations–a train kit, an architectural kit, and more. The prototypes were all made on an injection molding machine in Don’s dome in the hills west of Boulder. Sadly, they never came to market, but Don was kind enough to let me have his kits.
