This is the study of cymatics...has interesting implications. I loved your post. It's the first time I have received the words of someone's first impressions like that, and you expressed it magnificently.

I've been following the phenomenon for years. Never seen one for myself. I have noticed the precision of the designs...they seem computer-driven in their elegance. The one that mirrored the plaque we sent off about Voyager back in the '60s blew me away!

I have not given up that last bit of skepticism that allows for these to be made by humans. I'm not talking about jokers with ropes and boards. This would have to be a scalar technology, computerized and very tightly focused.
