Interesting. The meru foundation (meru.org) did a lot of work on the Hebrew alphabet. Stan Tennen the founder passed a year ago, but over his decades he produced a lot of thought provoking content for those of the mindset to investigate such thoughts. The content is still online.
Some of the things they did was to create 3D “ribbons” of Hebrew letters. Then you shine a light through the letters at various angles, it would project onto the wall and reveal all new designs. Some of which would of course look like double helix DNA strands and the like. And much more. One would have to be well versed to truly analyze and make connections like the one you posted about the Y in Egypt but that is, imo, the point. The more you learn the more is revealed to you as long as you remain truly open to seeing revelations.
In short, each letter would project new meaning into the world depending on how you looked at it. Or as the sages would say “there are 70 faces to the Torah”. You could spend a lifetime and not see them all. But one could try.

Quantum Torah is always fun!
Here's a case where he's using the half shekel for his example. The article is good, but the real treasure trove is all over that half shekel. It's one of those deep dive places that is its own mirrored but simple meaning.
(That's another topic right up there in secrets of the universe made simple.)
