Ghost of a flea

The dramatic designs for the 500-acre Olympic Park in east London have been inspired by the human form and the athletes who will compete in the Games. Plans for the main Olympic Stadium include a striking roof, which wraps itself around the venue like muscles supporting the human body.

Alejandro Zaero-Pollo, chief designer on the project at Foreign Office Architects, said: "We are trying to make the building communicate the idea of physical strength, sport and movement - this is what communicates the conceptual backbone of all the buildings."
