What does Central Park sound like? Kojima's piece explores this idea, taking 999 views of skyscrapers from the Central Park's Great Lawn, and generating hundreds of mini-compositions based on the RGB (Red Green Blue) values of the photograph's pixels. The art software selected a photograph from 999 views randomly, and made a short improvisation. Kojima named this musical form “RGB Music Renga”. Renga was a series of Japanese linked short poetry.
