I know this has been out there for a bit, but my wife just emailed this great presentation to me that she first found on Gawker. It’s an explanation of the subprime mortgage mess (how come the standard term for it has become "mess" rather than, say, "implosion" or "disaster" or "cluster@*$&"?) with stick figure art using Google’s online presentation suite. While this is a static presentation, you can even see on the right that someone could lead the presentation online, and you can tell who else is in the audience. I hadn’t seen Google Docs used like this before, and it might give you some creative ideas on how you can use it.
But enough of that. The presentation’s a riot. Enjoy.
