Graziano Cecchini, the man who turned Trevi Fountain blood-red last October, has pulled off another public stunt in Rome that he claims is a sort of protest. “It is an artistic operation that documents with art the problems that we have in Italy,” Mr. Cecchini said at the scene.

I tend to agree with the shopkeepers cited in the article. This is rather unimpresssive, especially when compared with the much bolder stunt pulled at the Trevi Fountain. And it's no where near as interesting visually as the balls bouncing down the streets of San Francisco in the Sony Bravia TV ad shown below.
