There was a neat demo in the science museum in London in either the late 80’s or early 90’s - they had an industrial robot arm (wearing a beret, of course) hooked up to a video camera, and some variety of edge detection running - and it painted portraits of museum visitors in a sumi-e style, with a brush. I’ve still got mine, aged 7 or so, kicking around somewhere, and from what I recall it was a decent likeness.
