Sure! I'm going to assume you aren't actually asking for a visual pun. 
Here is some code I put together:

#macro gear(gRad, gInset, nTeeth, pThick)
  //gRad		gear radius
  //gInset	teeth depth (from radius)
  //nTeeth	number of teeth
  //pThick	prism thickness
  #local nPoints = 4*nTeeth;
  #local tooth = pi*2/nPoints;
  prism{
   -pThick,pThick,nPoints
   #local V = 0;
   #while(V<nPoints)
    #local rV = (gRad-gInset/2)+cos(tooth*V*nTeeth+pi/4)*gInset/2;
    <sin(tooth*V)*rV, cos(tooth*V)*rV>
    #local V = V + 1;
   #end
   rotate y*180/nPoints
  }
#end

object{
  gear(1,.1, 30, .1)
  pigment{rgb 1}
}

It's just your basic gear, nothing fancy.

Why on earth would you do that?

Yes.  I would consider math more as a habit for myself.  People at work must
think I'm odd scribbling away trig and geometry equations on paper all the time
when I'm trying to work out some CSG postioning and such.

Nice image alphaQuad!  I'll have to dig and see if I have that model still.  It
is always great to see more LEGO/POV-Ray renders.

yes .... but it (math) explains so many things. the universal language 
right?

Actually, math explains nothing, which is why it's the universal language. :-)

A severe lapse of humor, evidently :(

Not bad, but increase the contrast: the gray shouldbe much darker in 
shadowed areas. Otherwise great!

Probably a question of ambient value in the finish.
