Minecraft is a 3d building game where you have an avatar in a world and you can edit and change that world. It is now the third highest selling computer game title ever and is a giant hit with children. It’s digital Lego! What kid doesn’t love Lego? Microsoft has recently paid $2bn to own this title and created a specific educational version of it intended for use in schools. Using data taken from a NASA shuttle mission I’ve shoehorned an accurate map of Colchester into the game and built a quick version of Camulodunum on the map. Schools will be able to use this map in class to study local history safely, again and again for less money than it costs to take them all up town on the bus once! Instead of looking at where the chariot track used to be they can get on a horse and race each other around a replica of the track.
