MOCKINGBIRD was typed on adding machine tape with my Underwood Standard Typewriter No. 5. It was originally intended as a mobius strip, a bottomlessness of consequence and contingency, but, "if that diamond ring don't shine..."

I started working on it in summer 2008 and stopped in fall 2011. The strip of adding machine tape measures about 40 feet long. It's incomplete on what I think of as the back side. Images of both sides are here:

I haven't decided what to do with the paper strip yet.
