The Guggenheim has a gigantic canvas that people can sign and doodle on.  Macy's first work of art is now on display at the Guggenheim!!  Woo Hoo!! 

The inside lobby of the Guggenheim and the entire thing is circular which is very cool to walk around and around and up and around.  There are rooms of art that go off the walkway.  Very cool design and very easy to not get lost in.
