Why would you use an array of 4 dimensions or higher?

Question

It is not because its complex to use but just adding another dimension increases the size of something by alot. What would you make that you'd use a 4th dimension?

My guess is that it is just a feature which nobody uses. Atleast I do not see the point of it yet.

Answer 1

It's only for fun, I think

Answer 2

Well if a 3d array were used for voxels (think Minecraft blocks) , a fourth dimension could store the content of each voxel at regular time intervals. So a Minecraft movie could be represented in a 4d array.
