Hmmm, giant puppets!
But it's weirder than that. I spotted this and this on FR and was a trifle dubious that this year's carnival in Nice had cloning as a theme. Cutting over to the official carnival web site I see that it is actually the "King of Clownery" not "Cloning" but that the theme is cloning as the floats and the web site attest. The non-Flash version of the site has mild stuff like two-headed clowns but if you really want to get creeped out, go in through the Flash side and find two-headed sheep and people walking dog-like clones of themselves. All with jaunty music. Boy that really gets me in a party mood!
