Spin Art (detail, two pieces)

Philadelphia-area artist Joe Dillon III invokes the legacy of Duchamp's readymades when explaining his mechanically assisted "spin art," but a closer spiritual ancestor may be the rotoreliefs. Dillon's art reproduces the chance operations of the rotating paint spray seen at carnivals on large-format pegboards. The end effect resembles a mandala, which is to say a rotorelief at rest (or enshrined in the museum).
