Looking for a way to rejuvenate your painting process? Try putting yourself on the clock. Force yourself to complete a painting in one session, for example, or take it to extremes like the artist featured in this video. He completes an entire work in spraypaint, in less than one minute. We might advise you not to try this at home, unless you have a supply of drop cloths at the ready. This may be the one painting process more messy than painting with pastels.
