Overhead Projector setup with Boom Arm for Dungeons & Dragons RPG
Benefits: Portable, easily adjust to pointing at wall rather than floor, doesn’t drill into ceiling.
Drawback: The boom arm can create vibrations that make the display shake if the floor has some give (like wood floors) and someone walks by the table. You can counter this by connecting a bungie cord to the wall to absorb the vibrations.
