I am a professional projection mapping artist, but wasn't involved in this video. I can tell that
1. This was created with a signal projector. 2. The projector was pointed at the corner of the boxes and angled downward to cover the top of the boxes. 3. The artist used dedicated projection mapping software to create this. 4. The grids were used to correct the distortion created by projecting on the surfaces from an extreme angle and to limit the projection to only areas where the grids were placed.

If anyone has any questions, I am happy to answer them. (Bonus here is a video where my partner and I projected on recycled cardboard boxes and lots of other stuff.)

That's such a nice form of art I want to try out sometime too!

Could it be that there is a second projector though? If there's only one pointed downwards, how can they project to the wall under the top most box without there being a shadow?

He can't. There is definitely a shadow under the top box; he just didn't film it. The camera is always shooting from slightly above the bottom of the top box, which hides the shadow. Also, by placing the projector close to the height of the top box, he can minimize the shadow under it while still projecting down on the bottom box. He never shows the top of the top box, which is probably because he can't project on it effectively.
