Collecting animations, videos, plotter drawings, digital paintings, and teletype printouts, “Computational Arts in Canada 1967–1974” opens at Western University’s McIntosh Gallery in London, Ontario. Curated by Adam Lauder and Mark Hayward, the show is the first historical survey of Canada’s contributions to early computer art and features drawings by Leslie Mezei and Roger Vilder, and Art Ex Machina, a series of silk-screen prints by international artists including Frieder Nake and Hiroshi Kawano.
