Hello Erik, I am very curious about your project, and was wondering if we could communicate over pm for some questions that I have? Thank you.

Thanks Frederick for your interest and nice compliment! Here is an article that might interest you (unfortunately in French but with a lot of drawings, code and formulas...) "Images dans un miroir sphérique" by Henri Bouasse

He treats about reflection in a sphere. It is clear from this article that the math and coding of reflection is way more complicated than anamorphism. Something I also realized during my "experiments".

This is one of his examples and he explains the math and geometry of reflection of spheres, cylinders, cubes, etc. in a special mirror.

Erik's Anamorphic Reflections Seasons (2D and 3D, cylindrical and sphere) are much more exciting and certainly more productive than "The Game of Thrones".

Something is similar. I printed a 3D spikey model ?top image?a few months before. Later one of my friends took a photo with a crystal ball ?bottom image?. It’s interesting to compare the result of spherical lens and spherical mirror. And notice their difference.

It's interesting to modeling a spherical lens with Mathematica. Later it's possible to combine mirrors and lens to build more complex optical system.
