                            RIPPLE THE WAVE
                                  and
                            ROLLING RIPPLE

   These are surprisingly versatile calls.  `Ripple the wave' is done
from
 a wave or line, and designates a person or two people.  It may
also
 give a number.  Without the number, the call is `<anyone> ripple
the wave'.
 (It is called that even if the line isn't a wave.)
 With
a number, it is `<anyone> ripple <N>'.
 
 Typically just one person
is designated in each 4-person wave (as in `side girls ripple the
wave'),
 and that person is an end.  That person does trades with
people until he or she
 reaches the far end of the wave.  If the
designee is an end, that is 3 trades.
 If the designee is a center, he
or she will work toward the center, and will
 do 2 trades.
Nondesignated people don't do anything except when a designated
person is trading with them.
 
 It is possible to designate both ends
(their second trade will be with each other)
 or both centers (they
will start by trading with each other.)  Other combinations
 won't
work.

   Instead of having to say something like `head boys' to identify one
person in each wave, you may be able to use more dancer-friendly
designators like

        end boys
        end girls
        center boys
        center girls
        lead ends
        lead centers
        trailing ends
        trailing centers


When a number is given, the designee does just that many trades:

          2G^   3GV   2B^   3BV             3G^   2BV   2G^   3BV
     
          1B^   4BV   1G^   4GV             1B^   4GV   4B^   1GV
     
                             end girls ripple 2


You can give fractional numbers to get interesting results:

   The call `rolling ripple' takes more than one number.  The designee
does
 a normal ripple of the first amount.  Then, whoever is standing
on the spot(s)
 that the designee(s) originally started on does a
ripple of the second amount.
 If there are more numbers the action
continues, from the same spot(s) each time.
