None of the elements here are individually surprising, but I had never thought of this, and it most certainly looks like it took ages worth of research and work to get working. The most surprising was the pinhole camera but now that I've had some time to think about it, it makes sense why it should just work. Very sophisticated, very cool. Actually, the most surprising was that this was a fun video and not just a long form blog post as I first assumed it must be.
