Who edits wikipedia?

A cool project using Google Maps to show who, when and what is being edited in Wikipedia.(via haha.nu)
This reminds me of Flickrvision-show who,when and what photo is being uploaded in Flickr and Gongfan-show who,when and what is he/she doing right now in Fanfou(a similar site of Twitter).
However,I can't see this site because wikipedia has been blocked in China.What's a pity!
