I had a friend in high school that constructed for a Science Fair project what he called 'Visualizing A 4th. Dimensional Hypercube' using a record turntable and colored lights. It was a sight to behold the lights flashing on and off to represent the cube. Needless to say, everybody including the judges were awed. He was a genius. He taught me how to play chess. Another of his projects was a high voltage dielectric pump. He was bullied in school, and later in life tragically, committed suicide. RIP Jim.
