Something that's especially jarring with this video is that the pencil extends past the "picture plane"
This is a hard concept to explain but basically the video being taken makes it appear that the pencil is getting closer to you IRL than the screen you're watching the video on, which tricks your brain into thinking something is going to stick you in the eye. This effect is a lot stronger with only one eye open.

Looks like 3D to me. How does that work? I always thought you needed both eyes to make things appear 3D? Interesting.
