Here's a design that's sure to knock your socks off. Hideyuki Nakayama designed a doorknob that let's you see what's going on in the next room. The coolest thing about it is its simplicity. There is no hidden camera involved. Rather, the glass knob is cleverly designed to reflect the room you’re about to enter, giving it a crystal ball effect.
Although privacy (or lack thereof) is sure to be an issue with a product like this, few would argue that this design is really clever. "A Room in the Glass Globe" is currently on display at the Plain People store in Aoyama, Tokyo, and is expected to be manufactured at a large scale soon.
