You surely have imagined it the way you perceive the movement of a car. But it's wrong.
I'll describe what it really looks like:
When the time period is so short that it's indivisible, nothing can move during this period of time – this is logical, because if something could, this period of time would be divisible. So when such the shortest periods of time, i.e. TIMEKS, follow each other, then the SHORTEK * KAZIUK long stick that is in motion at SPEED-C:
appears,
after TIMEK it disappears and at the same moment appears SHORTEK * KAZIUK further,
after TIMEK it disappears and at the same moment appears SHORTEK * KAZIUK further,
and so on...

So SPEED-C is not speed at which the distance of SHORTEK * KAZIUK is covered during TIMEK.
SPEED-C is the SHORTEK * KAZIUK long section that follows each other at one-TIMEK intervals.
Now look at my picture below.

In this convenient version of mine, in which SHORTEK = 1 mm and KAZIUK = 100, this section is the exact, 1 to 1, geometric representation of SPEED-C at one TIMEK.
This geometric representation of SPEED-C at one TIMEK, I have called STRINGOR.
But in MATHEVERSUM, STRINGOR is not a one-dimensional mathematical thing with only height.
STRINGOR is four-dimensional.
I cannot draw a four-dimensional figure, but I can draw it in a simplified form where two dimensions are put together into one common dimension.
When I look at the reflection of the inflated beef bladder in the two-dimensional surface of the mirror, I see the circle where two dimensions of the bladder a put together into one common dimension.
