This is a really neat little site
http://www.listentobitcoin.com/
It follows the blockchain and produces a chime each time a transaction is added as well as producing a bubble with the amount of the transaction in BTC with floats to the top of your screen.  It's like windchimes for freedom.  A couple transactions rolled by that were 13000 BTC and 29000BTC respectively...  That was just before the recent correction.  Those were millions of dollars changing hands.  As I type this there are 3 bubbles showing >600BTC...
