For all of you interested in the Edward Tufte powerpoint diatribe, the fallout continues... Here is his site, a link to purchasing his essay on powerpoint (I have the article if you'd like to borrow it) and a summary of the essay. Well, I'm off to convert all my lectures to 3x5 index cards. Wait... there are contrarians out there: here are two articles challenging the view: "in defense of powerpoint" and "people bore people". Regardless of how you feel about the tool (ppt that is), Tufte does have some cool stuff on his site.
