Klemens Torggler Doors / by Nicholas Taylor

My nose moved 15mm closer to the screen when I first watched this. I must have watched it another 15 times and am still in awe - but what is it about the this door that's so mesmerising?  It isn't just the clever geometry - it's just so perfectly weighted. The nonchalant flick of the wrist, the effortless rotation...

 ...just wish they'd put some Regupol under those squeaky floorboards!
