The main part of the Nio project is an interactive audio piece done in Shockwave. It consists of two "verses." In verse 1, the wreader layers audio and lettristic animations. In verse 2, the wreader both layers and sequences them. Verse 2 is a little sequencer. The Nio project has other parts such as the source code (requires Macromedia Director 8+); the (Shockwave) Song Shapes, which are audioless and use the same animations as in Nio; an essay on the poetics of interactive audio for the web; an essay on audio programming in Director, which is now part of the Macromedia documentation; still visual poetry drawn from onion skins of Nio animations; and an interview by Randy Adams with me about Nio.
