If you didn’t catch one of the four performances of Equilibre in Grand Canal Square, you may find it hard to believe that a JCB can be graceful. More than graceful, in fact: feminine, evocative, and even, in its sweeps and coy twirls, sexy. Yep, that’s what I said. Sexy. The Fringe has gone turned my head, clearly. But I stand over what I say: a mechanical digger was, for the length of a few short arias that filled up this wide open new Dublin space, sexy, or made so through some anthropomorphic feat in a balletic duet  that was unexplainably uplifting on a Saturday afternoon. Imagine what a combine harvester would have done to me . . .
