Kaws did stuff like this illegally all around the NYC in the past. Now it's mainstream. All types of graf will eventually become pop. Kids trying to rebel will have to think of different ways to show their individuality.
London graf artist[Fafi] was seen posing naked for what I do not know. Her art consists of cutesy yet racy girls painted in bright colors. I'm a fan but her work is much hotter than she is.
When I want to see ill art and gnarly tattoos, I visit the Rebel 8 blog[www.shop.rebel8.com]. These guys have a following that looks to be the hardcore scene. I don't consider myself to be in any scene but I do enjoy different aspects of a "scene". I wouldn't tat a Sailor Jerry style piece on myself but I do appreciate the art in it.
