At first glance, the Evolution Door designed by Austrian artist Klemens Torggler looks like a modern barn door, and we expected it to behave the same way – by simply swinging or sliding open. Boy were we wrong. As you can see in the video above, Torggler thought way outside the box when creating this fixture. With a single touch the Evolution Door splits apart into panels, glides across the wall and reassembles itself over the open doorway like a piece of origami. It’s completely mesmerizing: we could watch it open and shut all day! Read on to learn more about how the Evolution Door achieves this mind-boggling effect.

Although it looks solid, the Evolution Door is actually made from four separate, triangular panels. Torggler calls this system a “flip panel door” because the panels actually change places, flipping when activated to move the door into its open or closed position. The special motion “makes it possible to move the door sideways without the use of tracks” comments Torggler on his website.

Other movement mechanisms discovered during the Evolution Door’s development include a system of rods, and an epitrochoid curve, however Torggler found the triangles to be most efficient.

According to This Is Collossal, “the door is meant as a prototype, an extension of his artistic practice where Vienna-based Torggler has been creating similar kinetic doors for many years, several of which are available through Artelier Contemporary.”
