Sprinkle's work has always been about sexuality, with a political, spiritual and artistic bent. In December 2005, she committed to doing seven years of art projects about love with her art collaborator and eventual wife, Beth Stephens. They called this their "Love Art Laboratory." Part of their project was to do an experimental art wedding each year, and each year had a different theme and color. The seven-year structure was adapted to their project by invitation of artist Linda M. Montano. Sprinkle and Stephens have done twenty-one art weddings, eighteen with ecosexual themes. They married the Earth, Sky, Sea, Moon, Appalachian Mountains, the Sun, and other non-human entities in nine different countries.
