The Cube is a computer program that stores and repeats things people say on zephyr. It's a good source for really weird sayings that work well as signatures and away messages. For more info, see http://www.cs.cmu.edu/~scottd/cube-home.html, which is the Cube's home page.

Until recently, the Cube was the persona on Forum 2000 that answered every question. It didn't seem to be the brightest SOMAD, but it was always there for you.
