Anish Kapoor's Practical Art Piece, The Vanity / Sky Mirror from the other upside down side, showing iconic NYC skyscraper. .

Best enjoyed before cocktails upstairs at the Rainbow Room, unless dizzyness does not bother you.

Ladies, word of warning, no matter how tempting it may seem to have such a grand and flattering full length mirror at hand, do NOT try to sneak or fit this mirror into your handbag as it is 35 foot high and you will certainly not fit in a cab and the driver will complain and may even threaten to throw you out of his car, also you will probably end up squashing your phone and loosing a lot of important numbers.

( It seems to be quite firmly fixed on the ground anyway, I checked, unless you have a particularly strong Superman gallant type of a date.)
