Troika, whose shimmering flip-dot sculpture Cloud at the Heathrow Terminal 5 made them the darlings of a wide swath of art, design and architecture blogs earlier this year, will premiere a new commission this week during London's festival for the moving image onedotzero. Asked by the organizers to create a work that dually represents the festival's title and the theme "citystates", this London-based art and design studio produced a modern "digital zoetrope." Looks pretty dazzling from the mock-up above.
