The guys who are bringing Dungeons & Dragons (unofficially) to Microsoft's tabletop Surface system have been plugging away at their creation, giving us an extended, in-depth look at how one DMs the world's most expensive, most technically impressive campaigns.

The SurfaceScapes team at the Entertainment Technology Center at Carnegie Mellon University gives us a very clear explanation of how this project works, from the networked Dungeon Master laptop that controls much of the experience to just how the more fleshed-out interface will work. The SurfaceScapes guys have big plans for the project, some of which they tease in the above video.

Team member Michael Lewis offers the official Surface blog some expert insight into the creation of the D&D port, which budding developers and tabletop role-playing gamers with deep pockets will definitely want to read.
