Street Art, Homies.

Where I grew up, there's some interesting graffiti. The top two my sisters spotted while we were visiting home. On a wall, in giant black letters, is scrawled POOP. Somebody just really wanted to let the world know about POOP.
On a fence with green slats in the wire-work, somebody spray-painted Bohr's model of the helium atom and Einstein's Theory of General Relativity. Clearly, that is a tagger who likes SCIENCE.
The question I found written in between tiles on a bathroom wall at my college in my fourth year. I ran in to take a whiz and looked over to find somebody asking an esoteric but still probing question about identity.
The last one is just a picture of a kitty and the word "Meow!" It is on an electrical box outside my apartment complex.
