This reminded me of a friend’s story. They and another friend get high and go to a 3d movie. Mind you, my friend’s friend is missing one eye. They have only one eye. And they’ve chosen a 3d movie.

The movie is supremely underwhelming for this unfortunately monocular person, and so they get a highdea. They take off their glasses and start rapidly moving them from side to side, and saying, far too loudly, that they understand 3d now.

At this point, I have to apologize as I was laughing so hard that I couldn’t hear the rest of their story in anything but bits and pieces, but I think they ended up going to another 3d movie immediately afterward to confirm their findings.

… That’s actually possible that it made your friend^2 understand 3D. He would have manually turned the movie into a Wigglegram and I’ve read of people who finally ‘got it’ after seeing those.
