Found a link to this on the ResearchBuzz blog: WikipediaVision allows you to see in almost real-time, random English-language edits to WikiPedia according to where they happen on Google Maps. When you watch it in real time it gives you about 5-8 seconds or so to read the title of the entry that's being edited, and then click through to see the actual edit that was made. To just get a flavour of how the thing works I sped it up for you:
I've noticed that if it can't fully resolve the IP address it seems to just default to the middle of the country in question (either that, or there are a whole lot of edits coming from some small town in Northern Saskatchewan!)
