klemens torggler’s evolution door opens like magic

developed without the use of tracks, austrian artist klemens torggler has created ‘evolution door,’ a rotating geometric flip-panel door system that opens up with momentum. the clever structure is just one of the various concepts by torggler. he explains that ‘the special construction makes it possible to move the door sideways without the use of tracks. this technical trick opens up new applications for the door.’
