The Empire State Building is lit differently every night, and almost always with reason. Looking up at the ESB last night, I noticed that one side of the building was lit in red and white; the other was yellow and green (right). For these two weeks, it's in honor of the countries participating in the Olympics. Last night it was Japan and South Africa on the west and south sides. If you're in Manhattan and wonder what countries the colors represent on a given night between now and Aug. 24, you can always find out at the ESB Web site. That final night, it's all red, white and blue.
