Composed on an IBM Selectric typewriter. In a personal communication to Marvin Sackner, Cameron stated that this work was signed "upside down", is an experiment in which parts of the pattern have been dropped out and other parts (specifically the "single lines" which gave the original pattern much of its sense of curvature) remain. Different eyes will likely see different degrees of "wholeness" to the overall pattern in this variant. Original 2013. As far as the "upside down" business is concerned, I'd imagine you will be publishing the piece, if at all, right side up, and don't need to include the signature & date in any published versions -- they're there for you, purely for reasons of provenance. -- Source of annotation: Marvin or Ruth Sackner.
