LONDON, ENGLAND - MAY 16: Neon sign maker Bill Ellwood of Ellwood Signs works on bending letters into shape on May 16, 2011 in London, England. He has been making neon signs for over 50 years, with his son now following in his father's footsteps. The lettering is shaped over a hot flame, blowing into the end ensures the tube does not collapse. The pipes are filled with argon gas and capped with transformers which pass a high voltage electric current through the tube, causing the gas to light up. (Photo by Matthew Lloyd/Getty Images) less
