WARNING: PRODUCTIVITY SAPPING LINK

Pictures of Walls is a site devoted to...well...pictures of walls. But these walls have been "defaced" by some unknown passerby to create statements that range from political insights to plain old lewdness. You won't see any Banksy or Shepard Fairey here, only simple writings from the everyday vandal who needs to get something out of their system. There's something beautiful about the fact that these writers are obviously not doing this for publicity, just pure self-expression. But I warn you, once you journey into the vortex that is this site, something compels you to keep clicking....just....one....more....time...
