Better than none

Architect Mario Botta was asked to create a model of Francesco Borromini’s Church of San Carlo alle Quattro Fontane in Rome, to be placed near Borromini's birthplace on the shore of Lake Lugano in Switzerland. His sculpture used milled boards, fitted together in sedimentary layers, to evoke the negative space of the original church, in much the way that 3-D printing renders a solid object. It was dismantled in 2003 - too bad, because I would have loved to see this. Many more photos of this amazing work are here and here, and if you have a more scholarly bent, read about "The generative approach in the Botta’s San Carlino."
