Also, coming from California and living on the Pacific, I have sort of a "too much light" problem. I've got sunrise on side of the house and sunset on the other and skylights in every room. I had an optimized setup in the living room but when I moved my office to the spare bedroom I am totally blasted out by the sunrise over the mountains and shadows come across my face as the sun moves.

I'm experimenting with moving my desk but the trial and error is a pita.
