If it isn't time I have no idea what it is.

This is how I learnt it:
You can construct a 1-dimensional object (a line) by taking two points and joining them:

A •        • B => A •--------• B

You can construct a 2-dimensional square by taking two parallel lines and joining them:

A •----• B => A •----• B

                |    |

C •----• D    C •----• D

You can construct a 3-dimensional cube by taking two parallel squares and joining them in the same way. I'm not drawing that.

Finally, you can construct a 4-dimensional tesseract (or hypercube) by taking two parallel cubes and connecting each correlating point.
Since we only have three visually observable dimensions, most of the time the 4th dimension of 4-d hypercube is represented visually as permutations of the cube structure over time, which is why that picture you supplied is rotating like that.

I stole this image from Wikipedia and highlighted each cube so that you can see how each of the two cubes connect together.

Where... the... hell... is the fourth dimension?
I can't understand it at all! :(

Witch! Burn them! Burn them!!!!

I tried watching a flash about the ten dimensions but I sorta lost track after about seven. Shows how fantastic I am, I'm sure.
