Walking Roller Coaster WIN

This "sculpture" in Duisburg, Germany is designed to like a roller coaster. The catch: It's meant to be walked on. Designed by Heike Mutter und Ulrich Genth, the sculpture's 260 foot heights give passengers plenty to look at, though they have to marvel at the idea of the speed of the coaster at a more sane walker's pace.
