I’ve been watching the above GIF for the past half hour and it’s mesmerizing.

Supposedly, it’s a door, but I don’t think you can call it just a “door”. Austrian designer Klemens Torggler has been creating these dynamic sculptures since 1997, and no two are exactly alike. They operate in different ways, but each operates on the principal of counterbalanced weights which are bound at strategic points to create a smooth and seamless opening and closing movement. The GIF above shows his “double-rod system”, which is the most intuitive of the designs. The two sheets of metal are superimposed over each other, and slide easily into place.

A more intriguing design is the “triangle system”, which again is two superimposed plates, this time divided along diagonal lines, creating four triangles connected and mounted on a track. When in motion, the track pulls the triangles out of position, and when at rest the weight of the sheets pulls them back into position.

Torggler also tends to use multiple materials and unexpected shapes within his doors, such as these asymmetrical glass and metal creations.

Would you, like me, replace all your doors with these sculptures if you could?
