Matt Richardson's Descriptive Camera Project from 2012 is still an awesome idea. A little while after pressing the camera's button a little printer spits out a description like: "Looks like a cupboard which is ugly and old having name plates on it with a study lamp atteched to it." How it works? The piece of art sends a picture to an Amazon's Mechanical Turk service. Real people write the description send it back and the little printer does the rest of the work. Today this could be fully automated with image recognition AI. Personally I do like the real people aspect of the artwork.
