Pedestrians can now loop-the-loop!

German artists Heike Mutter and Ulrich Genth have created an aerial walkway in Duisberg, Germany called 'Tiger and Turtle - Magic Mountain'. It consists of a staircase which winds like a ribbon through space in the manner of a rollercoaster, and includes an 'impossible' closed spiral loop - surely an irresistable challenge?!

It also looks amazing at night...
