The closing ceremony will be a great end to these days of festivities - with celebration of the traditional Italian carnival which happens to be this weekend.
"The
show will combined the fantasy and colours of the Carnival with the
sounds and shapes typical of the circus and Art Comedy. 

The protocol moments of the ceremony will
alternate with the more informal and irreverent ones typical of the
Carnival. Thus, the clowns will come on to the scene, together with
snow explorers, the mermaid, interpreted by Valeria Marini, the
Carnival Court, led by the King and the Queen, and the Masks of the
Viareggio Carnival. And there will also be a tribute to Federico Fellini, seeing as six original costumes from the film ?The Clowns? by the master from Rimini, created by the Oscar Award winner Danilo Donati.
The audience will also be involved. As for the Opening Ceremony, all
spectators will be given a kit with angel and devil masks with a red
nose that lights up. Everyone will be invited to wear them, including
the heads of state and government and the other celebrities from the
grand stands. ?We will see how they will react to this joke? Finzi
Pasca smiles. It will take place on the occasion of the athletes?
parade, who this time will be parading all together and not divided by
nations, preceded by the flags of all the participating countries. The
Italian flag bearer will be Armin Zoeggeler, gold medal in luge.

Another official moment will be the extinguishing
of the Olympic Cauldron: with Andrea Bocelli on the stage, 400 maids
will walk into the stadium holding a lantern in their hands. Their blow
will lead to the simultaneous extinguishing of the Cauldron. Then, the
grand finale with the aurora borealis, the pyrotechnical fountains, the
live performances of two stars such as Ricky Martin and Elisa and the fireworks." (from Torino 2006 .org)
