Artist Klemens Torggler Reinvents The Door

Sliding, rotating, automatic, hinged. We thought we had a pretty firm grasp on the types of doors that exist in the world. How wrong we were.

This past week, a new kind of door, created by Austrian designer Klemens Torggler, has been mesmerizing the Internet -- and forever changing the way we look at this everyday structure.

"I can't stop watching this door open and close," wrote i09 Friday. We second that.

Dubbed the "Evolution Door," the clever geometric structure made its YouTube debut last June. (Watch the video below.) At the time, Torggler described his invention as a "flip-panel door." The artist has also said that the door has "soft edges" (for wayward fingers) and is "absolutely safe."

The "Evolution Door" is just one of several unorthodox doors designed by Torggler. All his doors are "based on rotating squares," his website reads, adding: "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."
