A Tesseract (4D cube) in Motion
This is a tesseract. Which is known as the 3 dimensional shadow of what a cube existing within 4 dimensions would look like. The tesseract is shown in a virtually 3-dimensional state in the GIF, and in 2-dimensional state in the bottom image.
It is really really hard to imagine the 4th dimension, living within 3 dimensions so the tesseract gives us the best representation we can imagine with our human brains. Here we collect posts, jokes, pictures about 4d (+4 posts - 4d)
