Here's a movie showing the concept animations, construction and testing of the London 2012 Olympic cauldron by British designer Thomas Heatherwick. Above: footage by LOCOG/Heatherwick Studio. Edited by the V&A museum.
The movie by the V&A museum shows the forging of the 204 copper petals and the testing of the concentric mechanised stems that rise in simultaneously to bring the petals together and form the cauldron.

After its debut, Heatherwick was inundated with messages of support from people “moved by his spectacular creation”, the designer told the Independant.
