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 3D image:
A funny curve:
The above graphics were created completely using math formulas and math softwares.
The example curve has nothing to do with the answer.
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.
(This curve is obtained from another surface.)
