This seems to be similar in execution to Google's SynthID. I hope they release actual code the technically proficient can use, unlike SynthID which can only (afaik) be queried with Gemini's UI.

G-code by itself only describes the series of motor movements over time, though I think it would be practically feasible to have a book contain an executable script, which would generate the same g-code as the one used to print the book. It would be really interesting to see how large the resulting book is.

Here is a similar project in the sense that it uses no connectors on the PCBs, using a SOIC-8 clip to bite into the board. I think it's pretty clever.
