Self expression

Specifically went in search of graffiti today. Not exactly difficult to find in the city. Seems to be a lot more than there used to be or is it simply that I'm now noticing it more. As a photographic subject, and as an outlet for individual self expression, I like it a lot. However, I suspect my view would be quite different (I'm thinking murderous rage and hanging's too good for the b*#stards!) if the canvas was my wall.
Lots more (colourful) stuff on Flickr
