   I seem to recall seeing programs like this.  I'm sure there are probably   
   many programs that do this sort of thing and it isn't that hard to   
   create.  They've probably been published as program listings in   
   magazines as well.  Unfortunately, I can't give any direct answer or links.   
      
   The ones I remember playing with did "3D" graphs which I found rather   
   cool looking at the time.
