Aaron Koblin used the same Velodyne lidar laser scanning system that guides robot cars in the DARPA Grand Challenge to make Radiohead’s "House of Cards" music video (the close-up shots of faces use a geometric scanning system to get a more detailed image). He has created visualizations of flight patterns over the United States and turned data based on long-distance phone calls and network connections in and out of New York into things that look more like art than boring charts. He unveiled his latest project at Etech: a Bicycle Built for Two Thousand, using Amazon’s Mechanical Turk to recreate "Daisy Bell," the song HAL sang in the movie "2001: A Space Odyssey" (which in 1962 was the first time a computer was used to synthesize music). The song is based on the combination of audio fragments sung by 2,088 people.
