Here are the new animation results (vs. the same two-axis rotation scheme I used
in my previous animation.)

Values used...
For the SINGLE-axis version:
object{OBJ
  rotate <270*rand(S),270*rand(S),270*rand(S)> // an arbitrary pre-rotation
  rotate <2540*clock,0,0> // one axis
  rotate 270*rand(S) // // to make the rotation axis arbitrary as well
  }

For the TWO-axes:
object{OBJ
  rotate <1210*clock,0,1950*clock>
  }

I'm still eyeing the results (vs. my 'expectations'), so I'll withold judgement
for now. I need to sleep on it ;-)
