It was nice, refreshing, slightly wierd.
Such things are always easy to spot, since there is a small crowd of tourists milling around, trying to photograph the landmark this way and that. So did I.
I get asked whether this is photoshopped. It is not. Strangely, I have had trouble finding its exact provenance on the net. I know the original fountain is called the Medici Fountain with a sculpture of Galatea by Auguste-Louis-Marie Ottin, but I could not figure out who put the “face” there, and why.
