Via frequent contributor Matt Rachmiel, George Washington University's basketball court will feature DC landmarks in the background. A visual depiction is available here.
GW's court thus joins the beach motifs of Miami-based Florida International University and California's Long Beach State, and the forest imagery of the University of Oregon, in paying tribute to the local geography and culture. Though it's only used for a conference tournament and not for an entire slate of home games, the Mountain West Conference's mountain-themed court should also be included in this discussion.
UPDATE: I also found a slideshow of hypothetical court designs of this type for several schools.
