Is it art when people staple egg cartons to a wool blanket, spatter it with purple paint, add xmas lights, and a picture of Richard Nixon? The answer is yes... I think of the models as the Canvas. Look at the work people do with coming up with clothing, textures, hair eyes, poses and expressions, lighting etc.... If that doesn't sway you think of photography.... Photographers are artists of light and compostion how would digital art be different?
