Making [etched] holograms with a pen plotter

Always happy to see Bill Beaty show up, even indirectly. This is a really cool phenomenon.

It’s like having a printer but slow and it breaks more often.

At least it doesn't refuse to draw because the magenta pen dried up or the replacement pen isn't the official one.
