Now this is one really cool video! Swedish professor Hans Rosling has made a career out of studying global well-being. The doc has been an adviser to the big players in the world health game, like UNICEF and WHO. A few years back he came up with the super-cool way to really ‘get’ the big picture issues with his Trendalyzer. For a look at this nifty, interactive software, check out the video – it’s a 4 minute peek at 200 countries over 200 years, with the help of a whole bunch of animated, bouncing balls.
