The size of money

This is one of those "because I think this is cool" posts. Somebody has digitally modelled exactly how big $10 trillion dollars is, physically: http://www.pagetutor.com/trillion/index.html

Interestingly, $10 thousand was a lot smaller than I thought, but $10 trillion was a lot bigger. I thought that familiarity would build accuracy (ok, no, I'm not familiar with a stack of $10 thousand in cash, but it is at least a number I can understand in terms of what it would get me; $10 trillion, not so much), but it doesn't.
