April 29, 2010. Paddy Johnson posted this on ArtFagCity last Saturday. It was originally seen on the Today and Tomorrow site back in February 2009. So consider it a re-re-post for a sunny and very windy day, without the LSD.
My gut feeling: had Tony Shafrazi encountered this sort of "movement" in 1974 at MoMA, he would have dropped his spray can in dismay.
