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?

I don't feel as if this is going to be especially helpful to you, but here it goes. I copied the image to a word document, and rotated it, looked at it from multiple angles, and etc. The best guess I'm coming up with, and this is a rather obvious guess, is that it's the framework for some sort of (possibly motorized) vehicle. If you figure it out, let us know.

A funny curve:

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

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.)

Cut off the upper surface above the horizontal plane

to get a funny 3D image.
