Here is an example[1], but it seems the official Flickr account has enforced all their photos to be darkened. EDIT: The Flickr blog post[2] explaining how it can be enabled states: "Flickr is letting members darken their photos — or the photos of others — for a 24-hour period" So anyone can go to the white house photostream, and darken their photos. Looks like the white house will be protesting against SOPA whether they intended to or not!
