I've started seeing a flip panel door gif make it's way into various random collection sites. But these sites had hardly any or no credit to the maker. Klemens Torggler, an Austrian designer/inventor created this and every once in a great while. He posts a neat short video showing off his creation. Check a few of his demonstration videos below of the flip panel door.
Even more information about this design.

This short clip demonstrates the door's unique soft edges.
