The Millennium Sphere was Cooper Union's submission for an international time-capsule competition sponsored by the New York Times Magazine. The project was designed in the Fall 1999 semester by professors Jean Le Mée and Manuel A. Baez along with a team of Cooper Union Students. The proposal was chosen as a finalist (honorable mention) and was included in an American Museum of Natural History exhibition in New York City. This website documents the Cooper Union's submission.

The "Ad Quadratum Construction and Study of the Regular Polyhedra" text describes the design principles behind the Millennium Sphere time capsule submission. It considerably simplifies and unifies the understanding of the structure of all regular polyhedra-convex and stellated-and integrates it quite naturally into a rich tradition of speculative thought be it geometrical, musical, astronomical or philosophical that has been part of our intellectual heritage for centuries.
