Oh, this is such a good idea, I can’t believe we didn’t think of it ourselves!
In conjunction with Design Tide Tokyo, architect Hideyuki Nakayama – a protégé of Toyo Ito – has teamed up with UNION, a manufacturer of door handles and levers, to create a glass globe doorknob. As you approach the doorknob you catch a glimpse of what appears to be another world, waiting for you to enter and join, but in fact is a reflection of the room on the other side of the door.
I suppose that if you didn’t care about people seeing what you were doing behind a closed door you could just, you know, have a window in the door, but hey, it’s still a cool invention.
