For years I worked for a law firm in the middle of this (one of the black glass bldgs. between the ball tower and the triangular building, and every day I was in awe at how the architects and engineers had the forethought to design the buildings where the golden glass faced the southwest and the black glass faced the dark and artificially lit sides of the city... the light play at different times of day is amazing. I always thought this would be a great subject for art, but all of the straight lines prevented me from doing it on canvas - a pain in the you know what. The wonderful tools in the applet make it possible to try something I'd otherwise never have done.
