Not sure what you're talking about. The "underground" lower level is all conference / presentation rooms. No one works there. The simulated sunlight you're referring to is a large art piece installation in the building and the creator chose to simulate light as he saw it during a particular sunset (in Arizona IIRC? It's been a while...) Check out the new SF office we opened up if you're looking for a more West coast feel.
