EvolutionDoor represents the penultimate stage of development of Klemens Torggler doors. The work was invented in 2012. It is the most prominent work of Klemens Torggler. Unlike the earlier kinetic works, this object moves from only one plane and unfolds into a third dimension during the movement process. It is definitely a work of art with impeccable utility and significant appearance, and like all other kinetic works by Klemens Torggler, a work with high spatial economy.
The individual squares are bordered with a soft and elastic material that acts as a pinch protection. The EvolutionDoor has been produced and presented in a wide range of variants, from minimalist objects made of wooden slats and paper, to variants made of solid wood, to elaborate objects made of aluminum or steel and with surfaces of glass or fabric.
