Criss-Cross was an artist's cooperative that formed in Colorado in the early 1970s. Having evolved out of Drop City, the 1960s artists' community, C-C focused on issues surrounding "pattern and structure" and became associated with the 70's art movement "P&D" (Pattern and Decoration).
In 1974, the five founders, Gene Bernofsky, JoAnn Bernofsky, Richard Kallweit, Charles DiJulio and Clark Richert, artists and filmmakers from Drop City, regrouped in Boulder, Colorado to start the new artist's cooperative. C-C's purpose, like Drop City's, was to function in a "synergetic" interaction between peers to create experimental artistic innovation. Between 1974 and 1980 the participants in Criss-Cross expanded to include filmmaker Fred Worden , University of Arkansas painter/printmaker Marilyn Nelson, and New York artists Gloria Klein, George Woodman and others.

This was an especially important venture for me, during which I developed my idea of the structure of space.
