William Hundley began in 2006 an ongoing series of photographs that he titled “Entoptic Phenomena” – floating fabrics as super ephemeral sculpture, lasting only a few seconds before reverting to their base position. The resulting photographs appear to have been made by computer manipulation, but there were absolutely no computer applications used in creating the images. A few of his “Entoptic Phenomena” photographs were featured in the 2007 Texas Biennial in which he was awarded the Juror’s Choice Award. (via)
