The London 2012 mascots will be introduced to the world tonight at 7pm.
Seb Coe, London 2012 Chair told the BBC Today programme this morning that the characters would be launched in a film
"It's a story by Michael Morpurgo, who I think would generally be considered to be one of our national treasures.
"I can tell you that they are formed from two drops of steel from the girders, the steel framework, that go to make up the Olympic Stadium.
"And they then take a journey between now and London.
"And they are fun - they are aimed particularly at children."
The designs will be shown on The One Show on BBC1 tonight at 7pm and after 7.30pm at www.london2012.com/mascots
