Composed on an IBM Selectric typewriter that was originally typed c.1964 and now retyped 2013. Cameron comments that this is what a Braille version of the optical pattern might look like. If exhibiting it, it might need to be lit from different angles to obtain different effects, and if backlit you can see parts of the pattern, selected by the patterned "weights" of my finger on the typewriter key, dependent to some degree on the rhythms of typing inherent in the pattern itself. It's also something of an homage to John Cage, with whom I briefly corresponded in 1964 or 5. -- Source of annotation: Marvin or Ruth Sackner.
