Why is it so satisfying when something fits so perfectly? Maybe we just like to see an efficient use of space? Maybe it's because seeing something fit like a glove makes us believe, even for a second, that some things are just meant to be. Like, there's some kind of divine force weaving the fabric of space and time together in a way that's actually neat and tidy. Maybe it makes us feel like there's actually order and meaning to our lives, and we're not all chaos, like a thousand pinballs bouncing into each other at random. Or maybe not. Here are some satisfying images of aesthetic perfection.
