I am fascinated by this innovative Evolution Door designed by Austrian artist Klemens Torggler. Two folding squares use no track and take up no floor space. They have soft edges, so there will be no pinched fingers. And yet it’s a door. Running kids and pets might have trouble with this, either unable to open it or tearing right through it (looks like fabric panels to me). Flimsy, perhaps, but still intriguing.
(I don’t know if it’s the floor, some really weird boots, or both, but that crunchy sound when he walks drives me crazy.)
Torggler has also designed a door using two rotating steel plates. Equally fascinating, but maybe not as safe. I can see this one in some upcoming sci fi movie.
And of course he’s designed a substitute for my sliding glass patio door, but I doubt the dog could wait for me to get it open. Nor does it look particularly weathertight. And do you see any locks? It might slow burglars, though, as they try to figure out how to open it.
(May 31, 2015: It appears the video of Torggler’s exterior glass (plexiglass?) door, which I had posted here, has disappeared completely from the internet. I did, however, find a photo of it.)
And here’s a GIF:
