Cayard's work had a distinctive cartoonish style, though the actual animation was generally in the hands of others, including John Canemaker for the early shorts and, for the later pixelated segments, ArtistMike. These later pieces were animated on an Amiga computer, but still reflected Cayard's sketchy design style. For some segments (such as "L Look Around Song" and "Me and My M"), Cayard composed music and wrote lyrics. For later segments, he wrote lyrics only with music usually by Robby Merkin or Phil Baron.
Cayard also produced animated openings and segments for Bob Keeshan's Captain Kangaroo, and illustrated several books including The Anti-Diet (1971) by Lynn Donovan McCann, It May Come in Handy Someday (1975) by Ann Tompert, and A Children's Almanac of Words at Play (1982) by Willard R. Espy.
