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.
This isn’t really a practical setup to replicate. Silverlight used an Epson brand projector to make the digital maps, and a cheap Epson projector should run you about $300 on Amazon. Still, it demonstrates new possibilities for playing tabletop role playing games. Roll20 runs in a Web browser. Maybe someone can figure out how to make this setup work using a much more affordable smartphone projector.
