Fascinating. It rather reminds of the grooves under the throat of a blue whale.

Thanks, Andrew. I didn't know anything about blue whales' throats before, nut after an image search I can but agree with you. A striking organic similarity. Thanks for [pointing it out.

Beautiful lines !!

Thanks, Jaap.

Awesome POV!

Thanks, William.

This reminds me, John, of the art of Bridget Riley. Best wishes, Joe

I actually took this to look like Op Art. It was only in editing that I discovered all the detail in back, which turned it back into a photograph,

Great optical interest in this image, John

Thanks, Diana.

Wow! This is just fantastic John! A stunning abstract image1

Thank you very much, Keith.

Fantastic, John !

Thank you very much, Ulrich.

An interesting type of perspective, that sorta causes one to think about what perspective really is - can one experience it without distance?

And, of course, an opening fan...
