- The reference I have to Shepherd's tones was a talk given by IBM's Richard
- Voss at SHARE 79 in Atlanta. He didn't actually desribe it as a fractal
- but used it to demonstrate the concepts of self-similarity. You _can_, if
- you listen carefully, pick out the point where a rising tone drops out
- and is replaced by one several octaves lower. Interesting effect, though.
