I just saw this: http://www.gapminder.org/ play the TED video. Then go play with things here: http://www.gapminder.org/gapminderworld/help/gapminder_world_help.htm This has been done by the Karolinska Instititet in Stockholm. The 'Create your own project' part does not appear to be ready yet, but I think that this would be a lot of fun to use. Laura
