FYI, to get "nightvision" you can just tint the screen green.

I have yet to look at the other resources, but I did want to make a comment on the scanlines in your screenshot: They are very much an artistic mutation of what would actually be seen. Scanlines were a defect of old CRT screens, and a good example of their visual effect can be seen with the image below:



With a cut-down version of that image, I ended up making this as a quick example of what scanlines actually tended to look like:

That said, if you dislike the pure realism, then try a simple alternating pattern that is 2 pixels or so in height. The primary issue with your representation is the fact that the lines are far too thin in comparison to the distance between them.

I was aiming for radio or electromagnetic interference. My roommate always called it scanlines and I guess it can look pretty similar

The difference being that the lines move across the screen.
I should have used broken lines or tilted it a little. It's been a while since I've seen something like that, my memory isn't very accurate.
But as for the scanlines that everyone tries to emulate for old games. I've never saw anything like that growing up. But then we used an 80's box set for 20 years before upgrading to a flatscreen. If TV screens were ever that crisp I'm feeling kinda jealous.

CRT screens were never particularly crisp, admittedly. As for the interference you're looking for, that's actually a result of several things, mostly a result of analogue signals degrading in transmission. (Especially through cords and cables and such.)

It's actually a variation of analog static, if you're curious. Scanlines like I tossed at you are caused by the screen itself.

Edit: avarisc mentioned to me that you may be looking for a Moiré pattern. That's the issue with the first picture you posted. It's the effect you get when you film an old television screen.

I'm not sure. The effect does look better when I use two line patterns moving over each other.
Here's a test project if anyone want to see it in motion.

The whole point of a Moiré pattern is that the overlapping lines are at different angles. That's how I created this:



That's a fairly good approximation (and overemphasis of) NTSC static. For reference, it's that same overlay from my screenshot earlier, plus a static overlay of horizontal, 4 pixel tall bars, plus a moving (and oscillating) overlay of 4 pixel wide bars at a 45 degree angle.

I like it. I'm going to see about applying a kind of mask so the static is confined to a monitor instead of the whole screen. For design purposes. I wonder if I can apply the same principle to create static snow. Before I was just alternating between 2 images of snow, but it doesn't have the randomness quality I would like.

Static snow, as in analog static, is definitely random. Moiré noise can create something vaguely similar, but it's not quite the same. In terms of applying it to a monitor rather than just the screen: easy, if the monitor is facing the screen directly. That enables use of viewports and the plane class to achieve the effect. If it isn't facing the screen directly (i.e. not a rectangle), things get iffy quickly.

Eh. Ended up looking like moving snow. I know flash animators just flip an image of snow around. But I'm doing this by means of rpg maker's show and move picture that anyone can use.
Probably would work better as a battle animation. But it's tricky filling the whole screen up with animation frames.

Not particularly. A single battle animation isn't much more intensive on the whole screen than it is on a portion of it, especially if it's only composed of one or two components.

A battle animation sheet would be smaller. But I think it's easier to control a single screen sized picture then it is to set up an animation slide by slide. copy and paste. And if you wanted the static to fade in and out you'd have to to that frame by frame. It's tedious. And I can't really predict what someone might need it for, you know?

I need to add static sound effects.

Sorry, haven't been on for a long time. These are so neat! Love em. I still remember those line distortions on the old tv, whilst playing my nintendo. =D
