Right? At least, that's the concept behind The Crouching Tiger and Turtle, designed by sculptors Ulrich Genth and Heike Mutter. Located in Duisberg, Germany, the giant structure is meant to help visitors get an unusual view of the city. It's an interesting alternative for people who hate speed but who love...climbing the stairs? However, like real roller coaster, some of the loops are upside–down, and therefore inaccessible to even the most intrepid climbers. The Crouching Tiger and Turtle is cool to look at, but would you try it?
