Congrats to the Grads

On this particular night (May 16), the
Empire State Building was lit up with a
pattern of blue/white/blue lights in honor
of the Columbia University commencement.
They're in the process of replacing the 400
standard lights they have now with 1,200
LED fixtures. See here. Now they'll be able
to create even more colors, and patterns too.
