The intrepid, charming and wise Delphine Blue dives into Leo Koenig Gallery to observe and document Gelitin's Tantamounter 24/7, a performance and exhibition featuring a homemade art-Xerox duplication machine. Gelitin, the Vienna-based collective, willfully dissents from the idea of art-as-mystery; the whole point of their slap-dash, jokey copies is their complete transparency. The group makes a point of steering clear of even a hint of artist-as-commentator, as everything about what they do seems determined not to be taken seriously (51 minutes).
