Well here's is a little easy photoshop tutorial. but it is a nice one;)
Make action-packed scenes from your average pictures!
Open up a picture with a person or an indiviual in it;
Duplicate the base-layer and delete the place that you need to focus on (note: i did the face);
Depending on where your gap is, add a radial blur by going to FILTER>BLUR>RADIAL BLUR (note: click in teh field to change the blur-middle);
Make both layers visible and add some lines with the line-tool;
Choose "Stroke Path" and click "Stimulate Pressure" (note: that way, it looks like the lines are moving);
Change the blending-mode to "Overlay" and the opacity to about 25-50%, and you're done...!
Well hope ya like it.
And let me see what came out of it;)
