Mama and Papa Op was an interactive family happening created for the Anderson Gallery, Buffalo, New York — an off-site exhibition space used temporarily during renovations to the Albright-Knox Art Gallery. Psychedelically costumed guides were available every Saturday to interact with visitors. The guides had special props and games that explored the world of optical illusions as an accompaniment to the exhibition The Eyes Pop: Op Art from the Albright-Knox Art Gallery.
