Did You Know? 2.0

Karl Fisch (assisted by Scott Mcleod and Xplane) has posted the reworked "Did You Know" presentation at YouTube. In my opinion this is a much better version than the original.
The beautiful but unobtrusive design allows the ideas embedded in the presentation to come to a much greater prominence over the glitz and flash that most presentations have a tendency to become.
Well done to those involved in its production. It's a piece that I'll be using not just to share the idea, but as an example of effective presentation style.
