With lines, or without lines, I can see them either way. And even though I've created a few stereograms of my own, I still find them utterly fascinating. This one is no exception. Nicely done, Gary.

Studying your use of lines in this one, I think I see why I didn't like the pinwheel stereogram I made that had the included lines. I've come to the conclusion that I made the line thickness too wide and they detracted from, rather than enhanced, the final image.

Off to check out your Japanese Koi stereogram,
