Note: On calls such as 
Magic Line In Roll Circulate, Out Roll Circulate,
  
Here Comes The Judge, Sock It To Me, 
  those doing the Circulate should identify themselves by making a noise 
  (say 'here' or 'me') and raising their hand.  Those doing the 
  Circulate do a normal Circulate
  since they are moving from an End position to another End position; the Others
  Flip one position within their 
Magic Line toward the End doing the
  Circulate.
