and i was wondering what effect did he use to make the video
I believe it's lens flare.
Well, he used a number of masks and overlays, some static... and other stuff too... not too sure about what, there's a lot of stuff going on. >_>
Generally speaking no click => done thing, though, if that's what you were wondering. Maybe just the static, which might be something from the riot gear, but that's about it.
