Ever notice how much high-minded graffiti is scribbled on the walls of university libraries? A staffer at the University of Chicago did and has been documenting it on a Flickr set that now has more than 700 photos. The graffiti often appears on whiteboards, but other times it's penned onto walls, around outlets, along baseboards and in the corners of study carrels. 

For a Friday distraction, take a stroll through the set. The graffiti is, in a very loose sense, an indicator of the mood of students in UChicago's Regenstein Library: often stressed, sometimes wanting to die, other times wanting to flee to Tibet. Here's one of my favorites, though the content is a bit coarse (edited by me to blur a phone number):
