Got more curiosity than energy to open doors? Then you'll want to get yourself one of these fisheyed globe doorknobs from designer Hideyuki Nakayama. The idea is resoundingly simple, the globe on your end of the door provides a wide-angle view of what's on the other side, which is achieved by collecting and reflecting light soaked up by another globe on the other end. So yes, privacy might be a tiny bit compromised with these door handles, but the fun coefficient should be through the roof.
