Gothamist has errected a petition to "send the Sony Corporation a strong message that they should reconsider their graffiti campaign."
The Sony graffiti campaign being the stenciled bits of false street art popping up in various metro locations in which little druggie looking waifs are seen groping their PSPs lovingly.

Gothamist's efforts are a more organized reaction to Sony's lame ads, the ones found out in the wild are much funnier.
