Cryptographic Magic Windows In article number 2101129, Francesco Pisani, Andrea Camposeo, and colleagues introduce stretchable and 3D printed cryptographic magic windows capable of generating complex patterns, including micro-QR-codes, by refraction of light in the visible range. The information carried by a light pattern, that is encrypted in the 3D topography of the magic windows, is unveiled by projection of the light pattern on a screen.
