35mm film stock, 50mm f16 lens. Still image from a 1972 psychological horror film.
The inside of a generic office building. A man in a lab coat fumbles with an incomprhensible mechanical desk-top machine. Behind him are windows looking into an enclosed laboratory, and we can see a mechanical apparatus with a hyper realistic human head with a full head of hair at the end of an appendage. The apparatus itself is an internal combustion powered analog computer to size of a filing cabinet.
