Shadow...

Being that my building is completely underground the way the building meets the ground plane is very important. The shadows or light wells could make or break the project. I want the ground to be folded and adjusted much like my map to create the light conditions. The light will cascade down the wall and infer on the ground the major directions and movement of the library. I held my map up to the light to see what kind of shadows the plane would make and it have me some interesting idea of how I need to design the light wells... I don't want the wells to simply be glass block floors on the upper quad that let light in but a series of folds and moves that create the path for light.
