Four-Story Pixellated Mario Mural
MasterPlaid writes "A group of anonymous cowards (eningeers) has apparently constructed a four-story mural of scenes from the NES Super Mario games. The best part is, they did the whole thing out of Post-It Notes, recreating the wondeful pixellated goodness we expect from Super Mario. The idea for this mural seems to have originated in the Strong Bad email of the same name."
If you think that's a cool giant pointless art project, then you haven't seen the Ice Tower (see the later pages, it only gets better).
