The January 2010 issue of the World of Interiors featured a stair that I just couldn't get out of my head; it looked so familiar. The Copenhagen police headquarters is a masterpiece of modern Neoclassicism from the 1920s that contains this gem.
This image looking up towards the skylight finally reminded me of where I had seen this before. Nature! 
The spiral stairs perfectly mimic the shape of a chambered nautilus shell. Does this prove that most beauty is derived from nature? Perhaps not, but it sure is an arguement for the statement!
