In that sense, stretching the cube of course doesn't make it an actual 4 dimensional object, but with the 4th dimension being time it makes as much sense to let that final stretching represent motion in time as it does to to let the previous one represent motion into a 3-dimensional space.
That's why I never called that object not 4-D as I've got no idea how that illusion would look like. I know it got the basics right. Extending a 3-D cube gives another cube as extra corners so to say. Every time the dimension increases, the edges dubbles in number and an equal strukture forms into the new dimension, like in thier demonstration.

And it's 3 room-dimensions and 1 time-dimension, they're separated you know. Wonders if time is actually only a 0,5 dimension, as so far only forward is known.
Now, make a graphical demonstration of how a particle moves through a 3-D space with time and displaying all the particle positions at the same time. You'll get a "snake" through space but how to represent time? (this is possible by "cheating" ) .

Now try to image 2-dimensional time , or better a 10-dimensional space with complex numbers, with 4-dimensional space, making a graphical representation having 24-dimensions

The funny part is that you can calculate on it.

And the formula for a 4-dimensional sphare is 16*pi*r^4/9 and it's volume is 64*pi*r^3/9 and I can prove this
Sadly this won't help displaying a 4-D sphare in 3-D, like the drawing of a cube.
