Mirror No. 12 is a screen-based work that processes live imagery captured from a webcam using custom software built by Danny Rozin. Using an image processing technique based on the rotational transformation of lines, the result is an impressionistic mirror composed of linear strokes. Darwinian Rotating Lines Mirror is inspired by Darwin's theory of evolution, in which random mutations become the basis for natural selection. Each mirror varies the following formal properties: line, luminosity, and tempo.
