> The stereographic projection makes it look like the animation in this post.

Couldn't be further from the truth. The image in the tweet is a huge improvement over the stereographic projection.

It is the same thing, with two tiny changes:

1. different-size projected squares are replaced with same-size circles

2. the tweet's image puts the north pole on a corner; the projection on the upthread link puts the north pole on the face.

Keeping the corner at the north pole does make it easier to understand, but it's still a stereographic projection.

https://github.com/HactarCE/Hyperspeedcube enables you to solve 4D cubes, the exploded visualization is standard but I think it is pretty cool
