Polish artist Karolina Żyniewicz will engage and confound during her month-and-a-half residency in the Croatian capital, highlighted by her fascinating “Sign of the Times: Collecting Biological Traces and Memories” exhibition. The exhibition is all about memory and the COVID-19 pandemic when medical masks and distance became normal almost overnight. For Żyniewicz, art is a way of perceiving the world, so visitors can expect plenty of consideration here. Excellent stuff.
