They'll be able to experiment as much as they want.

The last time money left the art world, intrepid types maxed out their credit cards and opened galleries, and a few of them have become the best in the world.

'The Panorama' is also the last place anywhere in New York where the World Trade Center still stands, whole, as it stood in the early morning of September 11. I can also see the corner where I saw the first tower fall and howled out loud. Seeing the buildings again here is uplifting, healing.
