A retro science-fiction laboratory illustration in a bold [late-1960s psychedelic screen-print and risograph style]. In the foreground, exactly two figures: on the left, an elderly bald male scientist in eyeglasses and a white lab coat leans over a large [orange] control console; on the right, a calm seated test subject in loose white clothing sits strapped into a heavy wooden-and-metal chair, connected to a circular head apparatus with thick black cables trailing downward. In the background on an elevated platform behind a railing, exactly three humanoid figures stand evenly spaced under hanging lamps. Overhead, exactly three large chrome dome heat lamps hang alongside three smaller pendant devices. The central console features exactly five small rectangular monitor displays showing profile silhouettes, surrounded by dials, toggle switches, and an auxiliary screen. In the lower left foreground, a separate vintage electronics unit displays a jagged [yellow] oscilloscope waveform. Background filled with warped optical rhythm patterns consisting of [wavy bands of fluorescent magenta, hot orange, lemon yellow, deep cobalt blue, and black]. Visual style features coarse halftone dot screens, posterized color planes, ink speckling, grunge paper texture, deliberate color misregistration, rough screen-printed edges, high contrast, and minimal depth of field.
