Input: Much of the art created at Upfest is painted on temporary hoardings, but murals on some venues - such as the Tobacco Factory and Red Point climbing centre - remain year-round until the next festival. Crowds watched 275 artists from 25 countries painting during live shows over the weekend. A family day is being held on Monday. Among artists taking part are Inkie, My Dog Sighs, Gamma, Lonac and Dutch duo Telmo Miel.
