Woman sits naked on rooftop in the name of art(Photos)

 A woman stripped naked and braved the autumnal weather on rooftop for four  hours as a piece of unusual performance art .
Puzzled passers-by couldn't believe their eyes when they spotted the nudist high above London's East End.
The artist, Poppy Jackson, was making the disrobed demonstration as part of an arty installation.
One witness, 29-year-old Raquel Rodrigues, was one of those taken aback by the strange sight.
She told the Evening Standard :

"I don't know how she got away with it - if I was walking around naked I'd be arrested.
"There are lots of businesses around, people were having a peek and then going back to work."

A description of the performance claims it "investigates questions relating to temporality, the body in site, representation and gender through consideration of the use of the body in performance as an activist practice".
