Hockney's novel thesis burst upon the public in the pages of the New Yorker (January 31, 2000) in an article written by Lawrence Weschler. Two years later, Weschler organized a major conference on the topic at NYU, bringing together artists, scientists, art historians, critics and more.

Michael Douma recorded part of the proceedings which he posted at: This teaching web site is based on that material. We are much indebted to all the contributors who generously made their work available.
