 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 artists' co-operative, Criss-Cross.Its purpose, like Drop City's, was to function in a "synergetic" interaction between peers to create experimental artistic innovation.Between 1974 and 1980, the number of participants grew to include the filmmaker Fred Worden (included in the 2002 Whitney Biennial), the University of Arkansas painter/printmaker Marilyn Nelson, and the New York artists Gloria Klein, George Woodman and others.
