One of my commenters, Tim, left a link to a site that has Math art, photographs of equation. He said that he would buy one of these and that maybe why people are buying pictures with numbers on them (I posted about it here). Math people love numbers.
Maybe the buyers are math people, maybe they are people who like to be a part of a trend, maybe they are people who think they’re making an investment, whatever. The question remains, is it art?
