### [Funny Math Art] Guess what's inside?

The surface in above image is a portion of the graph of
some mathematical equation.

Let's do some brainstorming:
Can you guess what's inside the surface?

A funny 3D image:

A funny curve:

The above graphics were created completely using math formulas and math softwares.

Hi benice;

I have no idea, what is it?

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Looks like there would be a couple of race car drivers inside the images to me.

### Re: [Funny Math Art] Guess what's inside?

Hint:
Consider the intersection of a horizontal plane with the surface.

The intersection consists of a family of funny curves.
(An example curve is shown below. It has nothing to do with the answer.)

Cut off the upper surface above the horizontal plane
to get a funny 3D image.

(This curve is obtained from another surface.)

Is it a pinball machine?

Maybe we can build a pinball machine which looks like these animations:

Hi gAr,

Yes, those are all my posts. Thank you for giving this subject your attention.

(Three different cross sections of the surface)
