They've put up a Facebook page, "Capitulation or Levitation: Occupy Atlanta takes on the Koch brothers." Here's what they say:
We demand that the Koch brothers withdraw all of their money from politics by 5:00pm on Tuesday October 27th. If they do not capitulate we will levitate the Georgia Pacific headquarters where they do their business. Capitulation or levitation? The choice is theirs.Occupy Atlanta is taking a page from the antiwar movement of the 1960s. Protesters threatened to levitate the Pentagon. It didn't work, but it got some attention.
