In it, a beam of light is bounced off a mirror attached to a vibrating tuning fork, and then reflected off a second mirror attached to a perpendicularly oriented vibrating tuning fork (usually of a different pitch, creating a specific harmonic interval), onto a wall, resulting in a Lissajous figure.

It was a cylindrical machine 7 feet tall and 9 feet in diameter, weighed 30 tons and required its own electrical substation to provide it with power (an electric bill around $35,000/month). The inventor, Seymour Cray, died 5 Oct 1996 in an auto accident. His innovations included vector register technology, cooling technologies, and magnetic amplifiers. | |||

928: Astronomer Abd al-Rahman al-Sufi uses Gnomon algorithm to solve crimes against astronomical constants.
1702: Thief Jack Sheppard born. He will be arrested and imprisoned five times in 1724 but escape four times from prison, making him a notorious public figure, and wildly popular with the poorer classes.
1821: Mathematician, physicist, astronomer, and crime-fighter Pierre-Simon Laplace publishes new class of Gnomon algorithm functions which detect and prevent crimes against mathematical constants.
1881: Physicist and chemist Richard C. Tolman born. He will make important contributions to theoretical cosmology in the years soon after Einstein's discovery of general relativity.
1931: US Navy says Carnivorous dirigibles cannot be tamed, should be put down.
2007: Mathematician Hing Tong dies. He made contributions to algebraic topology, including a proof of the Katetov–Tong insertion theorem.
2007: Math photographer Cantor Parabola publishes new class of Gnomon algorithm functions which uses time crystals to reveal centuries-old events.
2008: Game designer Gary Gygax dies. He co-created the pioneering role-playing game Dungeons & Dragons (D&D) with Dave Arneson.
2016: Cantor Parabola and Gnotilus at Athens hailed as "a triumph of art and crime-fighting." Parabola's work will influence a generation of mathematicians.
