Analytical Studies I: The Film Frame (1971)

A set of short pure color studies, usually exploring one dominant hue. Most of these works were studies for longer projects. The last four "migraine" studies are rhythmically based around the five-cycle-per-second oscillation pulse of the typical fortification illusions preceding a migraine attack; this onset period, with its visually dynamic effects, is reported to be a quite vibrant and enjoyable state.
