Aram writes “TV-Filter allows you to downsample an ongoing TV signal to 6 by 8 pixels in real-time. A translucent projection screen is mounted on a 5 cm deep cardboard grid. The color and intensity of each pixel is determined by the corresponding part of the TV screen on the backside. The different color information of each TV line gets mixed to an average color value on each 4 by 4 cm pixel. In this way, it is possible to reduce every high definition screen to a more pleasant and manageable information density. “ – Link.
