Amazing 3D illustrations

It looks a bit like a pop up book, but all the objects can be seen properly from a certain point of view. Otherwise it’s only a distorted illustration on a paper. This amazing work was created by talented Japanese artist Nagai Hideyuki (21), who describes himself as an anamorphic artist, which comes from Anamorphosis and it’s a “distorted projection or perspective requiring the viewer to use special devices or occupy a specific vantage point to reconstitute the image”.
