Nope, the movement of the thingy is in sync with the rythm too.
Here's the code that calculates the transform:

#declare Time = (frame_number-1)/25;
#declare Spline =
spline {
   linear_spline
   #declare Seed = seed(123);
   #declare C = -1;
   #while (C<=101)
      C, <rand(Seed),rand(Seed),rand(Seed)>,
      #declare C = C+1;
   #end
}
// Create the movement
#declare MoveTimeTranslate = Time+0.3;
#declare MoveTimeRotate = Time+0.3;
#declare PulseTimeRotate =
MoveTimeRotate-sin(MoveTimeRotate*2*pi)*0.15;
#declare PulseTimeTranslate =
(MoveTimeTranslate-sin(MoveTimeTranslate*2*2*pi)*0.15)*2;
#declare Trans =
transform {
   rotate <3,2,1>/12*360*PulseTimeRotate
   translate (Spline(PulseTimeTranslate)*2-1)
}

You can see the movement clearer in this animation which features a ball
with no tentacles:

Thanks! :)
