SurfaceScapes is a proof-of-concept platform being developed by students at Carnegie Mellon's Entertainment Technology Center (ETC) for playing tabletop role-playing games. Heir prototype was developed around playing D&D. Watch the video and notice how well tuned the user experience is to the tabletop format and to the gameplay. Players can use the elements of the physical game they love while leveraging technology to change the more labor intensive aspects (like creating the environments using paper and pencil). Gameplay also takes on a more visual role as actions are played out on the tabletop interactively. Well done!
