At the top of sse,(where the earth and the star projections are) I see all these different shadowed levels, it looks like maybe they were once building tops or something, but I cant confirm. Was there ever anything else here? or has it always been just a digital projection of stars and earth. Seems like alot of wasted space up there, the message is cool, but still seems like they couldve done alot more with such an open area.
