(VISUAL ART) In his debut solo gallery exhibition, Mystery in Which We All Participate, the always-enigmatic Juniper Shuey presents five video installations and a sculpture. Undoubtedly the work will blur the distinctions between the mediums and their messages. Spectators always become participants in Shuey's work and boundaries constantly shift or disappear altogether.
