For those who haven't heard of it,
Minecraft is basically the best game ever. Even though I don't have it.. yet. It's a massive (three times Earth) sandbox game for you to build your own house, and kill skeletons and punch sheep. Well anyway, your character can have a customised look, and on this
Skins website, there are quite a few to choose from, including several Doctor Who ones! Although it's not strictly Doctor Who, I still highly recommend the game. Thanks a lot to users phonik, onmizodd and an anonymous user for creating them!
There are also Futurama, SpongeBob, Star Wars, lots and lots of random ones and pretty much anything you can think of! Except for Torchwood and The Sarah Jane Adventures. And the proper game costs €9.95 (about £8.60).
Edit - Aaand, just today another Doctor Who skin has been uploaded. This ones the 4th Doctor! 'lholladay' made this one.
