As you may recall, I’m a defender of PowerPoint, rightly used. Today I came across a highly entertaining classroom video from Tom Wildenhain, a computer science student at Carnegie Mellon, demonstrating just how much is happening underneath the hood of this program (with hints that there’s more to learn).
Wildenhain’s lecture includes some theory for those who are interested, but mostly it comprises a series of captivating demonstrations, including one where an audience member asks a question that prompts a brand-new discovery. The video is 52 minutes long, and it’s simply charming. (via)
