I want you to create a fully immersive web experience called "Leonardo da Vinci's Workshop". The core of the experience should be an antique-style book containing Leonardo's actual designs and sketches. Use four of his most iconic inventions. When the user clicks on one of the designs, the original sketch should come to life as a fully interactive 3D model built with Three.js and WebGL. The 3D experience should feel polished, visually impressive, and actually demonstrate how the invention works.
