Hans Rosling's Presentation

Wow - I'm so impressed with Hans Rosling's presentation.  First I thought it was great because it was on a huge screen with the print being dark and the background being light so it was easy on the eyes.  Then it was unique because he used dots of different sizes and colors to represent countries instead of the usual bar graphs.  But didn't he ever get his point across when the dots started moving according to world changes while at the same time, the years in the background changed!  It was an eye opener as a presentation as was the substance of his talk.  It made the viewer totally get the message he was trying to bring across.  Then he changed to his discussion of world wealth and begin to drop layers to represent which countries held the wealth.  It was so incredibly easy to follow and at no time did he lose your interest.  This method of presenting data - through moving representations of each statistic - is the way to go!  It makes otherwise possibly dull information actually come alive for the viewer.  Very cool!  It did cross my mind though that the work behind it would be pretty intense.  Imagine having to add in each bit of data for each country and for each year and attach it to a visual.  Probably lots more time consuming than a bar graph.
