"This is a long exposure shot of an animation playing on a computer monitor - the animation is a video grab of a video feedback experiment. The streaks in the image are the paths moving dots smeered in time.
Video feedback involves pointing a video camera at a screen showing the output of the camera (I find analogue cameras better) which can result in stable animated feedback images if the right combination of contrast, brightness, magnification, rotation, focus, etc, etc...
It can take a while to set it up but it's hypnotically fascinating when you get there. For more fun you can introduce mirrors between screen & camera or a vision mixer / DVE unit between camera & screen."
Here's the original video feedback:

te recomiendo (si no los conoces ya) los trabajos de video-artistas pioneros como Nam June Paik y Wolf Vostell con generadores, monitores y magnetoscopios analógicos. Su trabajo se ha quedado un poco viejo, porque la tecnología que usaban se ha quedado muy vieja, pero sigue molando bastante lo que hicieron(más si piensas en cuándo lo hicieron).
