A new LED light fixture is secured to the side of a lift as crews replace existing street lights August 1, 2011 in Las Vegas, Nevada. The new energy-efficient fixtures are expected to reduce the city's annual electricity use by eight million kilowatt hours, saving about USD 400,000. The city estimates the LEDs will last about 15 years, nine years longer than the current lights. Funding for the project comes from federal energy conservation bonds and an American Recovery & Reinvestment Act grant. The city plans to replace all of its 50,000 streetlights after more funding is secured. (Photo by Ethan Miller/Getty Images)

British designer Alex Chinneck created the installation - called From the Knees of my Nose to the Belly of my Toes - by removing the facade of a detached four-storey house that had been derelict for eleven years and replacing it with a brand new frontage that leaves the crumbling top storey exposed, then curves outwards so the bottom section lies flat in front of the house.
