The Composite pattern is one of those design patterns you'll start seeing everywhere once you understand it.
In this video, I build a small game engine in Python to explore how the Composite pattern lets you treat individual objects and entire hierarchies the same way. You'll see why this pattern works so well for game scenes, file systems, UI frameworks, menus, and many other tree-like structures.
