I know it may sound like a newbie question but what is the best way of making an impressive ripple effect like this:

The water effect after the ripples is probably the map Displacement filter, but I want to know how to make good ripple effects. i was thinking about using after effects, but obviously file size is an issue.

Any suggestions would be appreciated.
