“Hobbies and inventions
Outside of his academic pursuits, Shannon was interested in juggling, unicycling, and chess. He also invented many devices, including rocket-powered flying discs, a motorized pogo stick, and a flame-throwing trumpet for a science exhibition. One of his more humorous devices was a box kept on his desk called the “Ultimate Machine”, based on an idea by Marvin Minsky. Otherwise featureless, the box possessed a single switch on its side. When the switch was flipped, the lid of the box opened and a mechanical hand reached out, flipped off the switch, then retracted back inside the box. In addition he built a device that could solve the Rubik’s cube puzzle.[4]

He is also considered the co-inventor of the first wearable computer along with Edward O. Thorp.[15] The device was used to improve the odds when playing roulette.”
