Who said you can’t re-invent the Door?
The 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.
I love the simple mechanical motion involved. I hope we see these being used in buildings one day.
