Nice try, but... not, that doesn't work.

(It makes ripples that are diagonal rather than parallel to the axies. 
And the ripples decrease in frequency rather than amplitude as they 
spread out. And there is no rounding at the corners.)

I am looking into making the function simpler though - but hopefully 
without loosing its "organic" quality.
