Math Encounters - The Topology of Twisted Toroids

Enter the twisted world of computer scientist and artist Carlo Séquin, where belts are cut so they double in length, donuts are sliced in half but don't fall apart, and surfaces pass through one another to make bottles where the "inside" is outside. Special introduction by Chuck Hoberman, award-winning inventor and artist, internationally recognized for the Hoberman Sphere and other "transformable structures."

In the late 1990s I used the idea of "twisted prismatic rings" to develop an algorithm that could determine whether a number is prime, and if not it could determine the factors of the number. Unfortunately it was no better than extant algorithms, and it was very tedious to use without a computer program, which I didn't know how to write.

wow, some of this stuff is hard to visualize
