One of the world’s most iconic cities just got two more (at least) amazing landmarks. As part of this month’s Other Ideas for Rio (a cunning recombination of the city’s “Rio” nickname), six public art projects will be on show in the city over September including a crystal maze in the Parisian square of Cinelandia, a “sound installation” by a Japanese artist at Arpoador, this amazing, ethereal head emerging from the shallows of Botofogo Bay(my old Carioca ‘hood!) and a sound and light projection on to the Arcos da Lapa by Brian Eno. Win, win, win! Such creativity bodes well for the city’s upcoming Olympics.
