This is my first attempt at creating a lithophane. I took my favorite picture of my nephew, uploaded it to designer and followed everyone's advice. Went on e-bay and found LED strip lights, power supplies, and switches. Now I have it mounted in a shadow box, unfortunately, I am having a hard time getting a good picture of it in the shadow box. Oh well. So, here it is sitting in the window. I think it turned out great.
Thanks for all the advice.
