I have to admit that this is one of those art things that just flew right over my head. This was a screen projection as you can obviously see of some grid line objects that are consistent with the overall architectural motif of the library. Past that I didn't get the point. The photograph would be better if it were a little tighter and thus cropped out the portion above the screen and along the right side. Straight on might be preferable to this angle but not was possible logistically.
