Art Criticism As Interpreted Through An Oft-Imitated Commercial Form

Designing and envisioning a piece of concept art requiring the use of Central Park: millions of dollars.
Petitioning the city of New York for permission to install your artwork: millions more dollars (and 20 years of your time).
Paying crews to erect your artwork over a three week period: the final portion of your $20 million.
Having a restaurant chain steal your idea to humorous effect: Priceless.
There are some things money can’t buy. For everything else, there’s your own personal finances and a nice copyright lawsuit.
