The 3D printing slicer Cura has a cool hidden feature: It turns out that you can upload an image and it will turn dark/light contrast into high/low elevation. You can use this feature to make a quick 3D-printable lithophane. Black and white images work the best, but you can get amazingly detailed photographic quality from lithophanes, so they don’t necessarily have to be simple… // Column at Shapeways
