The idea behind it is that an advertising company, new media artist, or interactive exhibit could utilize a group of these next to one another (or simply one alone) and make as large a "screen" as they wanted to.

This screen can render images in a 3D view or render actual 3D images in 3D since it has depth and multi-viewing angles. Or you can just make pretty light shows.
