Conner produced work in a variety of forms from the 1960s forward. He was an active force in the San Francisco counterculture of the mid-1960s as a collaborator in light shows at the legendary Family Dog at the Avalon Ballroom. He also made—using the new-at-the-time felt-tip pens—intricate black-and-white mandala-like drawings, many of which he subsequently (in the very early 1970s) lithographed into prints. One of Conner's drawings was used (in boldly colored variations) on the cover of the August, 1967 issue (#9) of the "San Francisco Oracle". He also made collages made from 19th-century engraving images, which he first exhibited as The Dennis Hopper One Man Show.
