A Graphlex large format camera (circa 1945) is used to project the image of an LED binary clock array (electronics scavenged from an Anelace clock) onto frosted glass. The clock is located in rear of the camera at the film plane. The clock image is projected onto a 90 degree mirror prism and then redirected to frosted glass. Alignment is tricky and spacing of all elements is critical in order to get "dots" of light properly sized and positioned on frosted glass.
