Interactive sculpture provides roller coaster aesthetics for those who would rather walk

The sculpture was designed by Heike Mutter und Ulrich Genth, and it looks like a roller coaster. Creators of the $2.75 million project say that the roller coaster stands for acceleration and high speed of a tiger but the visitor has to explore it step by step like a turtle. About 40 people at a time can enjoy the views from about 260 ft. over the Ruhr region via 249 steps, but the loops are inaccessible.
