I absolutely love Evolver. An impressive spiraling viewing structure constructed completely from wood that is located next to a clear alpine lake near Zermatt, Switzerland. Designed and built by second year students of the ALICE studio at Ecole Polytechnique Fédérale de Lausanne.
Spiraling a total of 720 degrees around, the Evolver offers a stunning view of the surrounding scenery. The Evolver is located next to the Lake Stelli at 2536 m (8,320 ft).
