 Hedrick’s contributions to art include pioneering artworks in psychedelic light art, mechanical kinetic sculpture, junk/assemblage sculpture, Pop Art, and (California) Funk Art.
 Later in his life, he was a recognized forerunner in Happenings, Conceptual Art, Bad Painting, Neo-Expressionism, and image appropriation.
