integer iteration;

       llSetStatus( 1, FALSE );  // turn Physics off.

          // position and the current time interval counter.  That is, 
          // use the iteration counter to define a rotation, multiply 
          // the rotation by the constant offset to get a rotated offset 
          // vector, and add that rotated offset to the current position
          // to defne the new position.

          position += rotatedOffset;
          
          // change the location of the object and save the current (rotated) 
          // offset for use during the next iteration.
          llSetPos( position );
