A post on The Big Picture in February 2008 points to a “cartoonesk” PowerPoint presentation explaining the current crisis in the financial markets. We all should have listened to it… There is no credit though for who created this file, also some explicit 4-letter words inside. (UPDATE, in slideshare an author is mentioned, not sure whether the person who uploaded it also created it)
For those who want to know it all in detail in a classic presentation packed with dense facts, I embed another presentation. It is not written in Presentation Zen-style, but most of the data charts are designed correctly. Viewing in full-screen mode is essential.
Making Sense of the Mortgage Meltdown
Update: Presentation Zen adds another explanation video here.
