does anyone know how to get this effect on a picture?

^ the street sign

^ the lady

^ the whatever in the background (CLICK FOR FULL SIZE)

^ the lady
do you see what i am aiming for?
its kind of a retro look with a bunch of small dots that increase and decrease.
is there a brush for that sort of thing?
