Perplexus

"The concept behind PERPLEXUS was created by 3-D design teacher Michael McGinnis in the late 1970′s as a project for an art class. Michael envisioned turning his creation into a toy. He had no idea this vision would turn into a decades long odyssey to get the game to market. After almost 20 years, Michael met the inventors at KID Group, one of the premier inventing houses in the toy industry. They collaborated on the design to make it more suitable for consumers. It was finally ready. The original product was marketed as Superplexus.
Through many twists and turns in the toy industry, Superplexus got tangled up in some changes and ended up being shelved just as it was getting started. But that isn't the end of the story...
In 2008, a group of enthusiasts contacted KID Group about licensing Superplexus. Perplexus, LLC acquired the rights to Superplexus and launched PERPLEXUS in its current form."
