A 4 dimensional object rendered in 3 dimensions being viewed in 2 dimensions.

that's just the 2D representation of the 3D shadow of a 4D object.

It's a 2D representation(because it's flat on your screen) of what a 4D cube would look like from a 3D inhabitant's perspective.
Just as a sphere passing through a plane would like like a circle that expands and contracts yet would also be viewed as a line that expands and contracts to 'inhabitants' of this 2D flatland.
This GIF shows the tesseract passing through itself because in those sections where it must reorient, it is not passing through itself, just passing by itself in a fourth dimension, but we cannot see that fourth dimension, so this is how the 4D cube would apear in our 3D world(theoretically).
TL;DR  it's still 4D, just what 4D looks like in a 3D world.

a 3D representation of aï»¿ 4D object on a 2D screen. **** this, I'm switching to an art major!

That's not a 4D shape, its impossible for us to see anything that's in 4D, that's just what we think a 4D shape, converted into 3D looks like

I'll explain
It's like drawing a 3D cube on a paper, now you watch a 3D cube in 2D.
That is a 4D cube, and since we live in a 3D world, we can only watch the 4D cube from a 3D perspective.

Explanation:
This is a 3 dimensional representation of a 4 dimensional cube (tesseract). This is a 3 dimensional representation because we cannot comprehend 4 dimensional objects because we comprehend the universe in a 3 dimensional reality. The 4th dimension is generally considered time. with time being the 4th dimension, and this being a four dimensional object, the object seems as though it's moving because we can only see any instant of the fourth dimension  time. if we perceived a four dimensional world, than we would be able to see all 3 dimensional objects, and inside them, and the nature of the objects through time all at the same instant.
The interesting thing here is that it isn't actually moving. We actually live in a universe of many dimensions (11 observable, at least last I read). Aforementioned, we cannot perceive four dimensional objects, so to represent them on a 3 dimensional plane, it must be moving to show its existence on a linear timeline.
TL;DR: it isn't actually moving. it only looks like it is because it is 4 dimensional (the 4th dimension is time) and we can only see 3 dimensions

actually, a tessaract is in 4 spacial dimensions, what that animation is is what it's shadow would look like if it were rotating. you can see the concept by making a wireframe cube and rotating it and looking at the shadow it creates. the cube makes a 2 dimensional shadow of several squares going into and out of eachother and connected at the corners, a tessaract makes a 3 dimensional shadow of several cubes going into and out of eachother.
so really, this .gif is a 2dimensional representation of a 3dimensional shadow of a 4dimensional object slowly rotating.

More ******** : every shape within this thing is a perfect cube. Also there are 8 cubes.

I am tired of seeing this on the front page. As a 3d modeler, I know how to do this, it is just a cube going inside out over and over. I spend a half hour making a .Gif to show you what it is on simpler terms

did some research.
this isn't four dimensional, it's an object with 4 dimensions represented in a three dimensional universe.

I like how everyone is copying the same comment to look smart.
Oh! By the way, that's just the 2D representation of the 3D shadow of a 4D object.
