After reading all this gibberish in all the forums this topic is posted in, I can only come to one gigantic conclusion:
Prof, you're wacked.
Instead of calling it a "sculpture", why not call it a "collection of about a bazillion things from other people all lined up in a couple of rows around the world that I won't live nearly long enough to see accomplished but that I want to take credit for anyway".
Let's leave the "largest sculpture in the world" title for the Crazy Horse sculpture currently underway in South Dakota, ok?
