cool graphics and gizmos

In my spare time, I've been making some cool models that use Flexsim's 3d graphics capabilities. I've attached four such models.
First, there's an improvement on my earlier surface graph. It graphs a user function z=f(x,y,t). It calculates each point once (instead of four times) and it has a smooth gradient of the colors. It needs to be compiled, but I have the model do it automatically.
There is a vector field plotter which draws a 3d vector field <x',y',z'>=<-z+3*cos(t),y+z*0.5,x+2*sin(t)>. All the arrows are the same length, and their brightness indicates their magnitude.
I also used the vector field plotter to draw the electric fields around two particles of equal mass and opposite charge in a stable circular orbit around each other. Only a Los Alamos native would think of using Flexsim for particle physics.

I'm going to ask the members of the forum the same question I've been asked around the office: Is there any use for this stuff out there?
