What is Public Sculpture?

... that's the answer Franck Scurti found back in 2005 or 2005 for an installation in the Tuileries gardens in Paris.

He gave a more extensive answer in the context of a show held in Grenoble in 2007.

And his point seems to be: Public Sculpture is open to interaction with the public. Hence the tags and graffitis. An answer I absolutely LIKE...
