I played with the 4D Rubik's Cube

For the time being, I found it interesting to click appropriately to mix it in a colorful state and then continue to rotate it lightly, but it is impossible to undo this (affirmation)

Right-click to turn clockwise, left-click to turn counterclockwise. If you drag it while dragging it, the whole will rotate. Ctrl + click on the outer cube to replace it with the inner cube. The place I touched is like this.

It seems that there was a movie in which such a thing appeared on the interface of a science fiction computer in the very near future ...

There are also applets that can move 4D 'hypercubes'. It looks three-dimensional when you wear 3D glasses with red and blue lenses.

Now you are a 4D person from today. As a matter of fact, human beings live in three-dimensional space + space-time, so it is a four-dimensional reason, but since we do not know what the next 'five dimensions' is, we mostly control and grasp time and space. You can't do that.
