Yesterday I "Stumbled Upon," literally, something I thought was very cool: a walking roller coaster. The structure is located at the top of a hill overlooking the Rhine in the city of Duisburg, Germany. The piece is called Tiger and Turtle - Magic Mountain and it was created by Heike Mutter and Ulrich Genth. It stands almost 70 feet in height and it's got a loop smack dab in the middle of it (I wonder how one traverses that!). The structure is fitted with LED lights, so interested walking enthusiasts can go for a stroll even after dark. The walking coaster opened in November of 2011 as part of a refurbishment project of the city and if I ever get to Germany, I wanna go!
