People just keep thinking of cool things to do with Flickr. Marcos Weskamp has taken the Flickr API and put together a cool social networking graph thingy. (great description huh?). What it does is allow you to see the relationship between Flickr contacts. Enter your Flickr e-mail address and it you’ll see a sort of flow-chart showing of your Flickr account and all of your contacts linked from it. If you click one of the contacts, it will then expand showing all of your contact’s contacts etc. etc. Give it a try… it’s pretty interesting to follow your Flickr lineage.
