3D

the opposite of 3D is NegaD. instead of projecting (or seeming to project) an object outward toward the viewer, it creates concavities. just as there were special cardboard-framed glasses for watching the early 3D movies, there are special NegaD clip-on lenses (also available as contact lenses) for the viewing of videos and stillpix made with this new technology.

be careful! some of the concavities are extremely compelling, and can pull the unwary out of his/her seat.
