Educational toy made in plastic versions. In the mid-1950s, more explicitly engineering-themed construction toys appeared, including plastic girders, columns, and panels that could be assembled into a model curtain wall skyscraper. Later, this Girder and Panel structural system was extended to a Hydro-Dynamic setup by adding pipes, valves, tanks, nozzles, and pumps to allow construction of model plumbing, HVAC, and chemical engineering systems like a simulated distillation column. Other extensions of the system supported suburban-style housing developments (Build-A-Home), or monorail transportation systems (Skyrail). The building toy Lego was originally developed by Ole Kirk Christiansen in Billund, Denmark, in the 1930s. The name
Super City (toy) Super City (toy) The Super City toy is a construction set produced by Ideal Toys in 1967. It is similar to Lego, small plastic pieces which are assembled to create complex structures. However Super City is more oriented to buildings and allows more sophisticated constructions. Children could build skyscrapers, research laboratories and pharmaceutical factories. Super City is made of plastic frames which connect at the edges with grooves and studs into which fit a variety of wall panels. Frames can be connected at right angles by grooved and flanged columns. Frames are primarily square with some rectangles (half squares) and
