The Paris-based, Canadian-born artist Kapwani Kiwanga, who makes intricate installations concerned with the African diaspora and questioning the traditional canon, used small glass spheres called conterie, or Venetian seed beads, as the primary material for her installation “Trinket” at the Canada Pavilion. She strung together thousands of them, in a variety of colors, to create a dramatic, cumulative effect, turning the seemingly insignificant objects into something vast and dramatic.
