Underground map from Facebook friends

[smudgedcat]

Hey everyone, I've been working on a little project for a while that I thought people here might be interested in. I've written an application that lets me create an underground map based on someone's Facebook friends.

If anyone is interested they can have a look at the website here: http://www.smudgedcat.com/mapper.

It basically looks for groups who are friends with each other and assigns them to the same line. There are generally lots of intersections between the different groups which makes for an interesting map. I've had several people tell me there was a connection between some of their friends which they hadn't previously realised.

I'm creating maps by hand using the software so I'm having to charge for them but at the moment I'm only asking for £3. If you like it then you can get it printed on a poster for only £10.

Here's an example of a map I've generated for a friend:

If it weren't for the 200 limit, I might have been tempted.
