evidence: On Saturday, an American artist estimated that "we are ill-prepared as a society" for image manipulation after having imagined in a video the Arc de Triomphe redecorated in LGBT colors, creating controversy among Internet users who believed this actual setup. The famous monument on Place de l'Etoile in Paris is surrounded by a giant rainbow and a sign titled "March of Pride" in the video released Thursday on Twitter and Instagram. However, this installation can only be presented in video form, as it was designed virtually by Ian Padgham, an artist who builds imaginary forms on videos that he shoots mainly in major cities. Some people thought that the Arc de Triomphe had in fact been redecorated and condemned a militant reappropriation of a monument dedicated to French soldiers. The 41-year-old artist was not surprised by this. "The number of people who take my videos for reality always amazes me. He explained that when I made one where the pyramid of the Louvre opened to let balloons escape, even Parisians believed that it was was true.
