Scared of roller coasters? Thanks to German artists Heike Mutter and Ulrich Genth, you don't have to be any more. Their recent sculpture, Tiger & Turtle - Magic Mountain in Duisburg, Germany., is a walkable alternative to Six Flags and Disney. Their impressive large outdoor sculpture allows visitors to climb up the installation and take in some amazing views in the process. Hit the thumbs for more images from Magic Mountain. [Contemporist]
