General technology overview: Looking Glass Portrait

I’ve been unable to find any hints at how this is done, but am very curious.

I understand acrylic glass idea, there is an outline in a patent.

I’ve browsed through site and couple of interviews with Shawn, but got 0 understanding.

Please give a hint?

For now my fear is that we will get some sort of lenticular plastic with super high resolution display glued to it.
