Organic Graffiti

I am generally an upstanding citizen of moral rectitude, very concerned with ethics and not being a jerk. Nevertheless, I am fascinated with witty vandalism. I lack the means/guts to become a witty vandal, but I do adore Banksy, the plastic bag subway sculpture guy, and people who figure out how to make graffiti out of moss.

I am awfully tempted to try this now.
