A friend of mine asked me the other day if I knew of any good sources of math art wallpaper as Google was not turning up anything very good. While I don’t have any specific sources of desktop backgrounds, I do have some great sources for mathematical artwork. Over the past few years I have participated in the Bridges Math Art Conference and the Joint Mathematics Meetings, both of which have exhibitions of mathematical art every year. There is a full list of these online math art galleries, and here is a selection of just one of my favorites from each of the four exhibitions that I have participated in:
"Harmonograms of Moscovich" by Ivan Moscovich. Analog computer originals. 24" x 24". 1968.
