Celebrities help build world's largest global sculpture

Celebrities including Big Brother's Jade, Chris Evans and Will Young are helping to create the world's largest global sculpture.

They have all chosen a shape to add to the internet sculpture at www.iconobloc.com.

According to psychologists, the shape people choose can reveal their true personality.

Dr Andrew Radcliffe says Jade's choice of a cube means she has a simplistic nature with few major points to get across in life.

Chris Evans' choice of a tetrahedron is an indication of a stressful mind and complicated lifestyle, he adds.
