* An impossible 3D structure is an object that cannot exist according to the known laws of physics. Impossible objects belong to the paradoxical sphere of neither existing nor non-existing objects. While they are fun to look at and ponder over, such impossible figures also reveal important insights into how our mind constructs a three-dimensional percept from a two-dimensional image.
