#2This is "old Internet" style fun territory (along the same lines as the Tom7 fun, if not quite as deep). I felt that the olive oil + fingerprint + phone screen was a really nice way to illustrate the core concept. Especially clever because it used something common and annoying to help describe how the plotter does its thing.

Maybe could swap out the pen for a needle?

There are very few TFAs I upvotes before opening TFA. But with such a title, this is one of them...

In fact, I believe that the article is describing a reinvention of this technique! Just with a plotter on oil rather than a compass on plastic.

Before getting further into the article I thought maybe he was going to show how to use the plotter to control the oil smearing technique, which honestly would have been kind of cool.

He did it on plastic CD cases, not oil. The oil in the beginning of the article was just for explaining the refraction that happens with the ridges in the structure.
