Gerber is much more akin to pen plotter code than it would be to the concept in the video. I used a pen plotter back in the 80's for generating check plots of my PCB layouts done on an early Racal-Redac CAD system.. Then we also got a Versatec electrostatic plotter, another interesting device. Monochrome, but good for schematics.
