Neither science fiction nor superversive per se, but still neat:
Dungeons and Dragons comes to life on digital maps
A projector combined with a Web-based tabletop role playing game tool make for a new and really cool way to play Dungeons and Dragons.
Reddit user Silverlight is a developer for Roll20, an online tool for virtual tabletop role playing game sessions, so he knows a thing or two about blending technology into traditional RPG play. By pairing Roll20 with a projector mounted on the ceiling, Silverlight is able to display digital maps on the tabletop for a home session of D&D.
