Instead of arranging photos in a traditional album, the site finds relationships among pictures and digitally composites them to create an immersive 3-D photo environment called a "synth." The best synths - like this one pieced together from the Apollo moon-landing shots - look like David Hockney himself Read more: http://www.time.com/time/specials/packages/article/0,28804,1918031_1918016_1918005,00.html #ixzz1RRRull6M
