Construx

Construx is a brand of plastic building toys introduced by Fisher-Price in 1983.

Unlike other building toys such as Lego, Construx feature beam-like pieces of varying lengths that snapped on to cubical connector knots in order to build large shapes.

Hinges, motors, wheels, and other movable parts expand the number of different shapes that can be built, and make moving creations possible.

For a short time near the end of the Fisher Price run, a version targeted at younger children was released called Basix Construx.

It used bright primary colors and did not contain the more complex pieces such as axles and pulleys.
