Vienna-based designer Klemens Torggler made the Evolution Door. This door may look ordinary at first glance but instead of the common push-pull method Torggler designed a smooth mechanism called ‘triangle system’ that let users flip the 2-piece door open and closed (like an origami) with a simple nudge.

Klemens Torggler’s door is an invention based on rotating squares, The special construction makes it possible to move the door sideways without the use of tracks. This technical trick opens up new applications for the door.
