【July 16 2015】Artists Heike Mutter and Ulrich Genth debuted this public, interactive artwork in November 2011, and it quickly attracted global attention. “Tiger and Turtle – Magic Mountain” stands in Duisburg, Germany’s Angerpark. At a glance, or from a distance, it appears to be a roller coaster. But it’s actually a walkable staircase that offers amazing views of the Rhine and the city. At night the handrails are lit up, making the installation accessible any time of day.
