Can Anyone identify this filter or effect?

It could be that the base layer was duplicated.  then a lined halftoned pattern was created using a layer with a 50% gray fill with a soft edge.  A selection was made of the the halftone layer.  Using the selection on the dupe layer press shift-ctrl/cmd-J to separate the dupe layer into two layers with the banding.  Then take the move tool and move one of those layers over until the image parts are move over to the next blank area in the layer below (you'll need to turn off the base layer to see this).  The move the other striped layer in the other direction, the same way.  Apply a motion blur in the direction of your lines.  If you want to make vertical lines, you will need to rotate the entire canvas 90 deg. to use the lined halftone pattern.
