I cut this out of 1/4" corian today with my CNC table using a rotozip as a router.
This is my granddaughter Lucie. The first photo shows the cut in normal light. The second one is backlit. The plan is to put this along with one of my grandson in a lamp as a Christmas gift for my Son and Daughter in law.

Gadget,
That's killer impressive!
Is the shading simply various depths of cut? The second one is like looking at a photo!
She's adorable, Gadget!

You are right on for the shading. The darker areas are thicker and the lighter areas thinner allowing more light through. I will make one of my Grandson as well and use them as a shade for a small lamp, when the lamp is on you have photos of them displaying.

The detail is impressive.
What did you use to translate the photo to the CNC commands?
Not sure if this was what you are planning to do, but if you mount it with the picture facing inwards, the picture will appear/disappear when the light is turned on/off.

The original plan was to mount with the cut inwards. However when doing that much of the detail is lost and the image gets fuzzy and weak. I cut to the depth recommended by the program but still it is not as good as with the cut to the front. As I play with this more, I will try to cut deeper which should bring better detail when the cut in placed on the back but I'm not sure how much better it will be. The corian costs about $5.00 for a 5X7 so I won't be experimenting too much with that.
I use Vectric PhotoVCarve to do the CNC coding, it is fairly inexpensive and very easy to use.

Here is a short video of how the lithopane responds to light.
