The Grim Fandango mural.
(By Jared, Gaea, Dale, and Violet, 2003) It's a replica of the wall one encounters at the end of a fantastic game called Grim Fandango. The design was copied from the (very tiny) sketch on the CD-cover. The original game artist saw a picture of the mural and was pleased.
During the painting of the mural, a very drunk and naked man (parents were staying in the dorms for graduation) stumbled out of a nearby room and loudly suggested the artists go home. He then noticed his lack-of-outfit and stumbled back inside. His wife offered a fumbling apology the next day.
