For his piece Steak Filter, Noah Feehan ran a video signal of a steak cooking through the actual steak. The deterioration of the video signal becomes a sign of how done the steak is.
Quite literally, I am plugging composite video into a big steak, which is then cooked. The video signal going through the steak is the image of the steak cooking. Gradually, the steak loses moisture and signal can no longer pass.
The videos don’t really show too much, but I love the idea. (via eat me daily)
