The last of the "yellow" pictures

This one isn't even nearly as yellow as the previous ones. I think I'm definitely getting older, as I see pointless graffiti like this and wonder "what were these people thinking"? I mean, the lines here are pretty elegant, but tagging a window seems like poor form, no?

I still am tolerant of nicely done graffiti murals, though. It seems like a lot of street art is simply vandalism, though: sloppy monochromatic spraypainting with no discernible message or artistic value.
