[Funny Math Art] Guess what's inside?

guess.png

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?

























Answers:

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.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

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

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:
