LookingGlass' small portrait display is more like (2D) lenticular. Their larger displays use a micro lens system that directs pixels out in beams in different direction. So you also get parallax in the up & down direction.

Well, I didn't know that it was only 1D lenticular (they keep that under their hat!) But let's pretend for a second that it is 2D lenticular.

In that case, yes it is absolutely the same as a hologram. Consider this thought experiment. Take a real hologram. Cover everywhere up except a tiny opening - a pixel effectively. Now what information does this pixel encode? It's just colour as a function of view angle.

Now do the same thing for a 2D lenticular display. You can reproduce exactly the same thing - a colour that varies as a function of angle. Therefore it is the same.

I guess you could consider LookingGlass to be a hologram in one dimension rather than two. Or alternatively it is a hologram if you promise never to move up or down!
