World Mapper

I'm reading Don Tapscott's Grown Up Digital which is, by the way, an amazing read so far. But one of the maps in the book is from a source called World Mapper . I'm sure others have seen the site before, but it is amazing to me. It's a collection of maps that can are resized according to different categories such as land mass, distribution of wealth, internet usage, and the like. There are animated maps as well. It's a fun site to explore and would be a great resource in all different types of classes.
