Weirdly enough I was looking at the in maths today, One of the Co-founders of Pixar used this in his work before founding Pixar to make an animation of a plane simulation, It's an amazing thing: It's called fractal, I couldn't find a full Gif of one but this one shows the main part, It's just something that from no matter the size, you don't know how big it is, because the picture seems to always go on, You never know when you're zoomed out or zoomed in.
