This week we are going to prove the library from last week. I put the Escher's work into the library and try to twist the book shelves in the organized hexagons to from a contrast room, and the orientation of the twist is followed by the degree of the fences.So the book shelves and the fence is twisted in same way. Also I add the line on the ground with the same pattern that Escher use in his painting like the right pictures shows, I put the lines on the ground to give people feeling of twisty.
