At least I did. In 1982 I designed and built a 5^3 cube, all in plywood. Although I did not aplly for a patent or other registration, as I was only a schoolboy by then, the local newspaper recorded this event. As the wooden prototype was not as speedy as necessary, I later designed a simulator for the Sinclair ZX Spectrum (a then so called 'personal computer' with an amazing 48K RAM memory). This simulator also included a 6^3 cube. 7^3 was not possible as this did not fit in the screen, which was my parents television set. Oh, those were the days! Nowadays I am an architect. Kind regards, Sytse de Maat P.S. If you happen to know other designers of 5^3, please mail me. [ Moderator's note: Can you describe the design that held the plywood model together while allowing it to turn? ]
