What does a trillion dollars look like?

Thanks to PageTutor we can try to get a better understanding of what the stimulus, bailouts and deficits really look like. Today I went to Treasury Direct, part of the Department of Treasury, Bureau of the Public Debt and visited "The Debt to the Penny and Who Holds It". The total outstanding public debt is 11,039,686,130,898.10 - more than 11 trillion. Even with the help of Page Tutor, I still can't really imagine it!
