Photoshop effect help needed.

I am trying to recreate the screen door type effect applied to the slideshow photos at the following sample website.

I am a photoshop newbie and would appreciate any help on locating a tutorial or at least the name of this effect. Thanks!

You could also try using the half tone pattern filter on a duplicated layer: Filter>Sketch>Halftone Pattern

Play with the number of pixels and contrast to how fine of an effect you would like. It will be in black and white.

Now change the blend mode to something like overlay or hard light and tweak the opacity to your liking.
