For those out there with artistic 3D printing capabilities...
I think it would be really cool if someone were to create and sell a low-profile building facade for that flat, lame sticker building picture on the backboard (to the right of the subway building). It would be light enough that it could be attached by double sided tape. Heck, a dimensional two building creation could be made as well to add even further dimension to that area.
Last time I remember seeing someone do that, it really looked awesome and added a lot
( Medisinyl created that backboard attachment for the vampire tower on the Alice Cooper ).
