How to add broken glass effect

This is a video tutorial I got from youtube on how to add a broken glass effect, I was looking at an NME magazine and this effect was used on the front cover and I thought it looked really attractive and original, it drew my attention to the magazine which is what I want my magazine to do so I looked on a tutorial on how to do it to see whether or not it would work with my magazine. However when added to my magazine I didn't feel that in linked well enough to my chosen genre so I decided not to use it.
