What is this?

Well, the screen has curvature, so it's most likely made of a thin sheet of plexiglass from a hardware store. Something like tissue paper is on the back of the screen to be a surface that the image will focus upon.

Under the table are projectors that are bounced against the mirrows and onto the screen. Alignment of the three projectors into one seamless image seems like it would be a huge challenge, but they did a really good job.

With the mirrors as part of the optic system, the projectors would need to be set up to project a reverse image.
