I was intrigued to come across these video demonstrations of Austrian artist Klemens Torggler's door designs.
You can read more about the design at Gizmodo. I'm sure it's clever, but what was wrong with the traditional type of door? Does this do anything better than the old design would have done? Is this intended to be an improvement, or just "art for art's sake"?
I'd love to know how that door design would stand up to problems like extreme weather, attempts to break in through it, and so on. I doubt whether it could be made as strong as a one-piece door. Yes, yes, I know . . . I don't have an artist's soul. Prosaic reality's more my thing.
