Explaining the SECRET of Penrose Patterns

This video is about a better way to understand Penrose tilings (the famous tilings invented by Roger Penrose that never repeat themselves but still have some kind of order/pattern).

This project was a collaboration with Aatish Bhatia (https://aatishb.com).
