Looking at those Demon sigils I'm wondering if any of them match Crop Circle patterns, at a quick glance they look pretty similar.

Since both are undoubtedly created by hoaxes and frauds, that's an interesting observation. I guess all artwork really is derivative.

It would be neat to trace that artistic lineage back to its sources.

Then again, there is a commenter on here claiming they look like circuit diagrams (whereas I look at schematics on a daily basis and see no resemblance). So stupid.

Almost certainly, given they can be made whatever shape you like and the overlap of interests.

I thought they resembled hockey playbooks.

They may or may not have been deliberately designed as apophenia targets. That is in any case what they are.
