David Lyon sent me a reference to this wonderful Dutch artist, Desiree Palmen, who makes painstakingly painted or modelled invisibility disguises to comment on the ubiquity of video surveillance. They are somehow more beautiful for their hand-crafted (as opposed to high-tech) nature. For the picture below, her technique was to take a photograph of the interior and then paint it onto a canvass designed to be worn by the subject, who was then photographed again wearing the painted canvass in place.
