This computer, built from Tinker Toys, always wins at tic-tac-toe. Danny Hillis and Brian Silverman began building it as MIT sophomores; the full story is described in the October 1989 issue of Scientific American in an article by A. K. Dewdney. It was displayed at the Computer Museum in Boston and is currently at the Boston Museum of Science. A community member writes that it "is a powerful illustration that technology is not only about Electronics."
