Looking up in NYC...
The Ribbon Staircase in the Armani store, NYC. Designed by Doriana e Massimiliano Fuksas, it is constructed from steel, glass and concrete.
Apple of My Eye
I took this standing under the Apple logo and looking up through the circular staircase and glass cube at the 5th Ave. Apple Store, NYC. I envision it to be sort of a mechanical iris around the Apple logo.
