When an eclipse occurs, there is an aftereffect that is not well understood. Shadows appear to oscillate, or shimmer. Scientists are not sure if it is more phenomenon than phenomena, which is the “addjective reality” I write about.
Look, for example, at the image I created called “strabismachrome,” published on wordpress and facebook. The image appears to oscillate. The effect is more an affect, a phenomenon derived from the way the elements of the observable object (the work of art) are organized to create (or effect) the affect (existing on demand).
See, for example, “The Added Identity” by griffith lighton, published on WordPress.
