This is a video Roger just found. It was done by the Los Angeles Children's Museum from my book, Bring On That Beat. The illustrations were done in black and white oil paint with colour shapes layered over them using the computer. I was one of the first illustrators to use the computer to create book illustrations....my first books using this technique were, ABC Pop, 123 Pop and Bring On That Beat. The first 2 titles were based on the Pop Art movement with an homage to such Pop artists as Andy Warhol and Roy Lichtenstein.
