From Gizmodo:
This glass globe lets you catch a glimpse of what's going on in the room you're about to enter.
Hideyuki Nakayama's "A Room in the Glass Globe," developed in conjunction with door handle manufacturer LEVER, shows you a reflection of what's going on in the room behind it, cast in a sort of strange, dreamlike haze. It's currently on display at the Plain People store in Aoyama, Tokyo.
