Oh - I wanted to mention that I understood what you wanted based on the magnified cat image in the original post.

That is not a "fish eye" effect.
This is a fish eye effect. A fish eye refers to an ultra-wide angle lens that can see most or all of an entire hemisphere at once.

To produce this effect with a sphere as I did, you have to modulate the IOR so that the part facing the camera is 1 and the part facing the subjects behind it is near zero.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
