“DO COMPUTERS WORRY YOU,” an exhibition of recent work by Canadian artist Matt Nish-Lapidus opens at Toronto’s Collision Gallery. Presented alongside “Greenlight: Carlaw,” a companion exhibition by Simon Fuh, Nish-Lapidus deploys assemblies of custom networks and Printed Circuit Boards (PCBs) combining “industrial and domestic materials, found texts, and bespoke algorithms” into a materialized polemic for more poetic (and personal) modes of computation.
