Now why didn't my library think of this?
Check out Pac Man re-enacted by humans at U. of Michigan (link directs you to the blog post about it at Boing Boing). At the University of Michigan, students got a study break when Pac Man ran through the library screaming while being chased by a ghost. I recommend watching the short video of the event.
Of course, it was students who did it, but at least they chose the library as one of their locations.
