Does anyone know of a macro or include file to simulate waves on the
surface of a fluid? I don't want to reinvent the wheel.
 I'm thinking of something like:

loop
          Buffer2(x, y) = (Buffer1(x-1,y)
                           Buffer1(x+1,y)
                           Buffer1(x,y+1)
                           Buffer1(x,y-1)) / 2 - Buffer2(x,y)
 
          Buffer2(x,y) = Buffer2(x,y) * damping
      end loop

I wrote something to do the job in QB but I am no programmer and
cannot get it to work with an array larger than 121 x 121.

Thanks Stephen
