Michael F. Chan's Visions of the Amen
This is an interesting sculpture... It is activated by sound (the singer in the video is Ashleigh Semkiw). Each string is activated by a different note and is has spin velocity based upon volume. It was done using Processing.
Pretty cool, but I wish the video was better at showing the strings transitioning from one shape to another.
