Antonio Gaudi, one of the most prominent architects at the turn of XIX and XX centuries. Known from his unorthodox attitude towards architecture. Although his biomorphic projects looked truly magic, they were quite controversial and, what is more, they caused many doubts. At that time, it was almost impossible to prepare the accurate calculations concerning the durability of the complex structures that he was making; however, Gaudi found the solution.

After having drawn his project, he was creating three- dimensional models of his structures in miniature. Subsequently, he was hanging home-made weights (which means exactly: sacks of sand) on the elements of this miniature structure. That was used for checking whether artist’s initial vision was possible to achieve. When such construction remained unaffected, then Gaudi could carry on with his work.
