I have inadvertently come across an underground culture that I was barely aware of... I walk by this wall of graffiti every single day on my way to and from work.
I've never really thought anything about it except that it would make a very interesting picture. Obviously I didn't really study the design because there is a web address right there! I only noticed that after looking at it on the computer. For those interested in this very misunderstood form of art, make sure you visit artthey.com
and take a look at their other works.
As for the image itself, it was taken with a Nokia E71, and post-processed by pushing up contrast and saturation.
