Giant mall mural captures face of America

Visitors to Washington over the next few weeks will have the chance to see a new addition to the National Mall. But it's not a monument or another museum, it's a giant portrait constructed from different coloured earth and sand.

The portrait is a composite of thousands of tourists who visit Washington DC, and is so big it can be viewed from space.

It was commissioned by the National Portrait Gallery and created by international artist Jorge Rodriguez Gerada who has done similar projects in Belfast and Barcelona.

Jane O'Brien visited the exhibition, which opens to the public on 4 October.
