Drawing complicated perspectives from life without the help of a pencil can be a funny brain teaser. Maybe it's because of this that I love this kind of jams. A good example is the entrance to the Escola Industrial. It's close to my home and I often cross it when I take a walk here and there.
When I started drawing it I got quite fascinated by the complexity of the whole and especially by the curious perfection of the tiles covering interlocking curved surfaces. Searching the Internet I found the architect Rafael Guastavino, the author of Can Batlló, a textile manufacture where the the school was located, and very fond of this type of roofing. Shortly after this project Don Rafael went to the United States and registered a patent of what was just an improved version of the traditional catalan vault. And hit the jackpot. His roofs are at the Carnegie Hall, Grand Central Terminal, the American Museum of Natural History, Ellis Island Great Hall, the Cathedral of St John the Divine and many other buildings... all this just in New York. Dozens of his works can be found throughout the United States.
