This slightly strange website shows Wikipedia edits from around the world. These are anonymous editors with IP addresses so the location can be noted. I got it from a list called ResearchBuzz. This is what RB says: "I like tools like this because they put a nice element of randomness in my brain -- pages and topics presented with no context or introduction. It's like a mint for my skull."
Try it for a couple of minutes and offer your brain a mint.
