As part of the winnings, Adobe is donating software and 3D printers to Waters' school in his name. "The semaphore had been transmitting the audio broadcast of Neil Armstrong's historic moon landing in 1969," reports The Mercury News. "That's right, not the text but the actual audio." The report provides some backstory: "Waters discovered the project, San Jose Semaphore, last summer while he was looking up something about Thomas Pynchon's 1966 novel, 'The Crying of Lot 49.' The text of that work was the code originally programmed by New York-based artist Ben Rubin in 2006. Seeing there was a new message, Waters began trying to decipher it while watching and writing down the sequences online from Tennessee. He discovered a pattern that led him to believe it could represent a space -- or a silence -- in an audio file, and when he graphed the results it looked like an audio wave. He dismissed that as being too difficult but came back to it and eventually ran his results into a program that would convert his numbers to audio. The first results came back sounding like chipmunks squeaking. So he tweaked things and found himself listening to the historic broadcast, which ends with Armstrong's famous line, 'That's one small step for man, one giant leap for mankind.'"
