I was attempting to simulate Light Probe images, which can be thought of as taking a picture of the reflection in a mirrored ball (like a silver Christmas tree ball). Not all images seem to work well as Light Probe Images for emaps. Some need lots of smoothing, at some point during the process, to produce good results.
I've been playing with a script to do this, which basically does what I manually outline below. While this method produces a cool effect, maybe someone can offer suggestions on how to improve the technique for simulating Light Probe images.

Note: You can also get interesting results by running the script twice: once at 10% Circular Warp Depth, then on that result, run again at 100% Warp Depth.

Hey Tux, how exactly do you make these e-maps using an image?
You can do it manually using Filters/Polar Coordinates.
Step #1 - Run Polar Coordinate using these settings.
Step #2
Image/Transform/Flip Vertically
Step #3 - Run Polar Coordinate using these settings.
