Austrian artist Klemens Torggler has created a prototype called the Evolution Door, which opens and closes in an extremely unique way. Currently, the door is available in glass, steel, and wood version, utilizing triangles that fold out to move the door in one variation and rods that rotate two square panels to move the door in another variation.
The door has been classified as a “flip panel door” and certainly could be a revolutionary idea in how we build and install them in the future.
Check out how both variations work in the videos below:
