Passing time with trash. In this artwork titled “Sweeper’s Clock,” the hour and minute hands of a clock are formed by two people sweeping waste in real time. The performance is part of artist Maarten Baas’s series “Real Time,” a set of four works in which people’s actions present the passage of time as a physical, labor-intensive process. See this work in #LifeCycles, a new exhibition exploring how design can offer new strategies for repairing our planet. Learn more and plan your visit → mo.ma/l
