Do you know what this is? This is unicorn. And, this art is made from egg! Do you believe this? I was surprised at this picture when I saw it first time. It is made by carving a eggshell into statue. It carves just a little and it begins to pattern. The thickness of the egg is 400μm. (1μm=0.001mm) So, 400μm is 0.4mm. It is difficult to see the size of 0.4mm with the unassisted eye. I think this is very detailed work.
