Austrian artist Klemens Torggler took the IKEA-styled sleek look to another level and developed the Evolution Door. This four panel door is styled with a modern look, almost something you would expect to see in a science fiction movie, but the functional aspect can make anyone forget that aspect very quickly as this design is a space saving dream. The best thing is that it only takes a simple nudge of finger tip to enter or exit any room making everyone feel like a king at each entrance. There is never a need to get worried that kids might squash their fingers in the door as all the sides of panels are designed with secure edges.
