The Mobius Bench

I've always been intrigued by the Mobius strip--you know, where you take strip of paper and make it a loop, first giving it a half twist? According to Ivars Peterson: "Ever since its discovery in 1858 in a purely mathematical context, the Möbius band has played a role not only in mathematics but also in science, engineering, literature, art, music, dance, crafts, playthings, puzzles, and magic tricks." The latest discovery: You can sit on them, too. Actually, the bench pictured here has been at the Shops on Lake Avenue in Pasadena, California since 2003. Read more about it here.
