### AI overview

This article explains hybrid images, a visual technique in which different images appear at different viewing distances. It connects examples such as the Mona Lisa, Salvador Dali's work, and the Marilyn Einstein image to Fourier analysis and the use of mathematics, science, and programming.

### Source excerpt

The Mona Lisa Leonardo da Vinci's Mona Lisa is one of the most famous paintings of all time. And there has always been a discussion around her enigmatic smile. He used a trademark Renaissance technique called sfumato, which involves many thin layers of glaze mixed with subtle pigments. The striking result is that when you look directly at Mona Lisa's smile, it seems to disappear. But when you look at the background your peripherals see a smiling face.
