Video — Halftone
A clip rescreened as a halftone: one averaged sample per cell drives the size of a dot, square or ASCII glyph, rebuilding the picture from luminance alone.
Moving footage rebuilt as a dot screen: a lattice of white circles on black, each swelling where the frame is bright and shrinking to nothing in shadow. The picture only resolves at a distance, the way a newspaper photograph does.
Each cell's colour comes free of charge by drawing the native frame into a buffer one pixel per cell, so the downscale does the averaging. Luminance then sizes the glyph — a dot, a square, or a character picked from a dark-to-light ASCII ramp — in a single mono colour or the cell's own video colour, with an invert switch flipping the screen to negative.
