This multi year study began as a simple question. Could light falling through the thickness of a constructed opening be the genesis of a wall with calibrated  aperatures corresponding to times of day and the seasons? A simple “sunbox” of calibrated openings unwittingly  became a kind of camera capturing the daily sweep of light over the course of a year.
