The Six String Sonics / The Six String Stairs (their website can't seem to decide on the official name) in opposition to traditional band setups, are instead a group of musicians that are each equipped with a single-string guitar.

They make the interesting argument that, because an average guitar has 6 strings compared to the 5 fingers on a hand, a human's creative capability when creating music with the instrument is more limited than it could be. By spreading out the strings between six people, you can distribute the music and obtain more creative melodies and awesomeness. Check out the demonstration video, keeping in mind how each of the repeating guitar sounds eventually combine to form a wonderful piece of music. It's positively Electroplankton-esque!
