Eye-frazzlers
The old observatory on Edinburgh’s Calton Hill may be the most favourably positioned art venue in the world. Recently resurrected by a group called Collective, the space, with its panoramic views and Enlightenment history, is an ambitious and imaginative addition to Edinburgh’s art scene. In their Hillside gallery there’s a firing-range warning sign on the screen, a few seconds of stillness and silence, then a sudden machine-gun rattle. The sound is revealed to be a stick, dragged by a child along corrugated iron, and the juxtaposition is the strongest moment in Helen McCrorie’s portentously titled video work, ‘If play is neither inside nor outside, where is it?’ (until 6 October).
