Global Rich List
Seen this One Page application site doing the rounds and its actually worth a mention. ‘Global Rich List’ compares your annual earnings to the rest of the world’s with the use of smart calculations, animations and infographics. Give it a go!
This website has unfortunately been redesigned or gone offline, so I have removed the direct link to it. The screenshot below hopefully preserved enough of the design but if you are really keen to inspect further, try this Archive.org link. FYI: the site was first featured on 29 April 2013.
