It seems like the era of low-tech video processing is upon us (again). The earliest devices were being built in the 1950s and 60s by people like Mita, and they aren't well known today. So we get a whole new set of approaches, like this one (with video) or this one where a TV has an attachement that breaks the image into derivative pixels based on what's on screen.
