Corian Color Lithophane Lamp!
Try saying that fast 5 times!
I made the entire lamp out of 1/4 inch Corian and cut the Litho with a 45 degree V-bit. In PhotoVCarve I set it up as a 0.03 ball nose bit with max depth at 0.15" and line spacing at 16%. I set Z-zero at -0.05, with the max depth at 0.15" I got more of a 3D effect than I would have at 0.1". I used a 23watt fluorescent light bulb and an outdoor light fixture.
