Hi Jim, thanks for this helpful project and your nice post here: http://coffeeshopphysics.com/articles/2012-12/22_lost_in_hyperbolia/ I'm wondering how you rendered the first image in the blog post above: splash400 any possile chance for sharing the source? thanks!

I almost certainly used The Gimp, but I'm sure I wouldn't be able to find the sources now, 8 years later.

They're both Escher works—the leaf with a big water droplet on it was originally all grayscale with no hyperbolic tiling inside. I probably scaled them both up, aligned the hyperbolic tiling layer as well as I could over the leaf (temporarily setting the upper layer to 50% transparency so that I could improve the alignment by seeing through it), and then maybe used iWarp to adjust for the water droplet's non-sphericity. At least, that's how I would do it now.

Got that. I'm considering using Escher's image as texture in a POV-Ray scene, that's way I'm interested in your image. Anyway your work is impressvie. Thanks for your reply.

Not that I did this correctly either, but Escher's works might not be out of copyright. So depending on what you'll be using it for, that might matter.
