This image provided by Google shows the Google doodle of Wednesday, May 23, 2012, a fully functioning special interactive synthesizer honoring the 78th birthday of synthesizer pioneer Robert Moog. Moog died in 2005. The Moog doodle, a replica of the Minimoog Model D, may not be a highly complex synthesizer but it explores a lot of the realms of synthesis. (AP Photo/Google) less
