What should we do as a society to combat unrealistic images of celebrities due to the widespread use of Photoshop? Rant and rave on a blog? Publicly shame them on sites like Photoshop Disasters ?
Or, you could take it back to the streets, as was done on an ad of celebs in a train station in Berlin; the geeky street artist affixed a Photoshop menu and commands  onto the smooth faces of Christina Aguilera  and Britney Spears .
Public comment plus geekiness? I'm all for it.
