This work was inspired by a Hubble telescope image of the nebula NGC 6357 and is a piece of visual music in which the processes for synthesizing the sound and the video footage are closely linked. An algorithm for generating cellular automata has shaped the voicing of the repeated chords in the opening passage (and in subsequent recurrences of this texture) and has determined the selection of pitches in the more pointillistic passages that provide contrasting textures. The pitches are tuned in a 5-limit just intonation and are sounded by physical modeling instruments developed for the Kyma by Harm Visser.
