Pan Troglodytes: For some reason when I try to quote anyone, I'm unable to. However, thank you for acknowledging that there was something to find. I'm crazy, for sure, but hopefully in a "productive member of society" kind of way.
But as for that beauty, working through this puzzle, even if I was on the wrong path, was often sublime. I've had so-called mystical experiences (I'm an agnostic, so don't put much weight on them), but this puzzle shows that coin_artist knows her stuff.
I'm not talking directly to her because I think she'd prefer that we explore it all on our own without dragging her in. The fun really is in the exploration, and a true artist prefers to let others do the interpretation.
If your wife wants to explore the image, I'd recommend the tiff version. The jpeg worked fine, but became pixellated a few dozen steps in, and the detail in the tiff is worth a slow computer.
Thank you I will tell her. But I know what will be the response: computer graphics is not necessarily her means and besides - it would just be a copy of your art.
