I am currently working on a piece myself. It is 1 web page, it's basically all white with a single question mark dead center. This page will be available for $5,000,000 US. The museum that purchases the page will setup a computer terminal and provide the ip address of this terminal to me. It will be the only terminal in the world able to view the page. It is a one of a kind work of unprecedented rarity. Museums can conatct me via the contact link. Serious inquiries only.
