Immersion is a seriously cool web app from those brainy kids at MIT Media Lab, because here's what it does: Converts your entire Gmail history into a visual network. Here's what mine looks like above, my whole history of Gmail use since 2004, based on my interaction with 1,318 collaborators, sending a total of 118,771 emails. (Yes, the app counts that data too.) It's deeply personal me, but I can see pretty much my whole life history from the last 9 years in this graphic -- jobs had, people known (and still know), and how they're related to each other. If you look real close, you'll see more than a few avatar names in my network. Go here to start creating a network of your own.
