Giant Number 4 Made From Discarded Umbrellas

Art installation 'Shelter', a giant number 4 made from discarded umbrellas by artist Stephanie Imbeau, winner Channel 4's BIG4 public art competition, stands illuminated in front of the Channel 4 building on March 4, 2009 in London, England. The piece, a representation of channel 4's logo, is constructed from unconnected blocks so that it only appears as the number 4 from a certain viewpoint.link
