Say hello to Michael. He's one of the developers on the Surfacesapes project over at Carnegie Mellon University, and he's about to walk you through just about the best use for Microsoft's Surface multitouch table in the video above.
Oh, what's said "best use," you ask? Why, recreating the Dungeons and Dragons tabletop experience, of course!
It's still a work in progress, but so far they've got everything from modeled pieces (such as the Dire Wolf you'll see), spell effects (such as the massive explosion that takes out the aforementioned Dire Wolf), and tons of nice touches, from the terrain to the ambient, outdoor sound effects.
Check out the video below for more on how the Surfacescapes project is bring D&D to the world of multitouch.
