"In Motor Reliefs, the revolving sports wheel rims stop, start, speed up—present the illusion of turning backwards—and then slow down. There are nine different brands, their features accentuated by tyres that are comparatively thin, while the silvery light flashes elegantly off the radiating struts, sometimes turning to a blur. For lovers of art history, Carr’s project cleverly combines ‘Boy Racer’ culture with the optical experiments of Marcel Duchamp that the work’s title refers to. At first all the glowing wheels seem identical, but gradually the distinctive characteristics of each one becomes apparent."
