The app MirrorLab on Android has a very interesting Julia Effect, and I'd like to recreate this effect in Mathematica. Here are some examples of input images and their outputs:

inputs = Import /@ {
   CloudObject["https://www.wolframcloud.com/objects/09bf1cae-1109-4490-a35a-960ff9199863"], 
   CloudObject["https://www.wolframcloud.com/objects/17390d2b-3271-4c7c-9f0c-190db3d81b8c"], 
   CloudObject["https://www.wolframcloud.com/objects/2cc137f2-6a2f-4cd9-9792-97c4df3a98b3"], 
   CloudObject["https://www.wolframcloud.com/objects/5c1ce239-7fe8-4636-a008-eae8fad0bff8"]
 }

enter image description here

effects = Import /@ {
   CloudObject["https://www.wolframcloud.com/objects/c3f3e2ef-2a66-474d-a031-fb078353e0da"],
   CloudObject["https://www.wolframcloud.com/objects/2e6f5a50-09a3-469c-b8cf-5418fa4f4c83"],
   CloudObject["https://www.wolframcloud.com/objects/af56d7cb-11c0-421a-8759-bac6ed20d250"], 
   CloudObject["https://www.wolframcloud.com/objects/fbfdb34f-3ea1-4f99-912f-b9cfa47b0ea7"]
}

enter image description here

I think they are using some sort of shading function. I've been playing with ImageForwardTransformation, but can't seem to get this to work.

    $\begingroup$ The images in this paper were mostly prepared with Mathematica. I could post an answer with code later. You might be entertained by this web page as well. $\endgroup$ – Mark McClure Aug 16 '18 at 20:27

    $\begingroup$ @MarkMcClure that would be great! Have you tried the MirrorLab app? They seem to have a bunch of different families of transforms in addition to this type. If you don't have an Android device - just use the Blue Stacks on your mac. $\endgroup$ – M.R. Aug 16 '18 at 21:51
  • $\begingroup$ @MarkMcClure any chance you can show us your solution here? $\endgroup$ – M.R. Aug 27 '18 at 21:07
