How would you go about creating a static like effect in Java / Slick2D? What I mean is like the static found in the Main Menu of Left 4 Dead 2. I was thinking just creating a transparent image sequence the size of the screen that has small dots placed everywhere and then setting its opacity to somewhat low in the code. I am going to try this out now, but would anyone have a better idea on how to do this?I’m guessing that you want a noise effect:

There are a bunch of different noise techniques. I’d look into them, because then you can generate random static instead of the same images over and over.
