A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
There are some 4d experimental games. One is a space flight Sim that allows players to move in a fourth dimension, entering and exiting physical space in a semi physics-compatible way. It's really fun and it tends to break your brain a little.
What's the game?
Itch io has several, I can't find the name of the one I tried like 10 years ago. It was just a proof of concept, a freespace like fighter.
There's also one that turns Minecraft into 4 dimensions, or it at least cribs the aesthetic of Minecraft. I forget which. It's been a few years.
