“Perceptron” is an autonomous video feedback system using concave and convex lenses, prisms, servo motors, and digital filters.

“The Perceptron, say, will use computer graphics and automatic recognition of shapes (not just contours and silhouettes) – as though the chronology of the invention of cinema were being relived in a mirror, the age of the magic lantern giving way once more to the age of the recording camera, in anticipation of digital holography.”- Paul Virilio, The Vision Machine
