The Crisis of Credit Visualized does a great job of giving a visualization to the current credit crisis. The description is a little too simplistic, but it’s one of the few I’ve seen that doesn’t point fingers and stays balanced.
(If you think finger pointing is necessary you might see that as a flaw. On the other hand it’s nice to talk about this stuff without seeing the phrase “fucking [name political party here]” on there.)
Worth a look, even if only for the excellent display of difficult concepts visually.
