3D funicular structure + Rope Physics + Optical illusions

A twisted very humble tribute to Antoni Gaudi's amazing work with funicular structures used for the fabulous Sagrada Familia in Barcelona. This genius architect was inspired by nature, its shapes and its laws. He was using an experimental technique called "funicular structure" to model his building by hanging ropes with weights on a roof. When gravity made it stable, you put a big mirror below and watch what you see. You can then report this structure on the ground and it stands (demonstrated in theory later).
