Singapore Art Museum (SAM) launches “Open Systems,” an online exhibition exploring how virtual space is “for rehearsing alternative and novel modes of social, political, and spatial organization.” Cat Bluemke, Total Refusal, and 20 other artists will present works in the coming months, while Alice Bucknell and Lawrence Lek share video essays at launch; the latter’s Pyramid Schemes (2018), repurposes the parkour gameplay of the Assassin’s Creed series to illustrate a polemic about architectural aesthetics.
