I contribute to this project (they use my 3278 font) but I think the best way to do this would be to have shaders available to compositor windows. This way, any terminal app (or video player) could tap into a library of CRT shaders. The only thing missing would be frame-to-frame data availability to make persistence possible - Windows Terminal has shaders, but they can’t access the previous frame.

I believe compositors like picom can already do this.

I used to daily drive this, most of the effects were minimized but I found that a little bit of white noise really helped make my terminal a lot easier on the eyes to read. I wonder if it is related to how some people find that film grain has a pleasing effect. For those looking at the screenshots note that the terminal is incredibly customizable, you don't have to have all the effects dialed up to 11! Sadly bit rot…

Fun fact, you can use Ghostty and vibecode the shader you want. In fact, the other day I used Claude Code to create me a custom CRT shader.

There is a thing that cool-retro-term is lacking: Letters showing up on the screen the instant you press the keyboard button.

As a user of a dec vt220 on a college vax vms, I can assure you, that did not happen on all old hardware.

I like the idea and used it for a couple years, but the lack of functionality was a bummer.

Ghostty with shaders on the other hand gives me all the functionality AND the effects. Some people may not have figured this out yet but you can stack multiple shaders on top of each to get some really cool combination effects.

Have any videos or pictures you can share?

Super fun but so much not for me. Fricking awesome if you're in the TV or movie business trying to get that effect right. Reminds me of the first time my artist kid used the term "pixel art", which in my memory brings back only frustration from my 1980s restriction to 2, 4, then 16 colors. I love unlimited colors, thank you very much. And I remember being grateful to pay $1,000 for a flat screen monitor around 1995 or so. I adore the crispness of digital output.

Again, not criticizing this effort. Just saying that I love being here in the 21st, thank you very much.

People go so overboard on this stuff, the amount of ghosting on the DOS example is insane. I don’t want to spoils anyone’s fun but that’s not really what most screens looked like back then.

Agreed. It’s sad but I think that unless you were born in the 70s, you may not be old enough to have seen enough CRT terminals to know the difference.

We need at least one CRT terminal in each city so that kids have a chance to experience a real one.

Don’t underestimate how many of us were raised in hand-me-down computers.

Those of us born in the 60s also recall many variations of CRT terminals.

I had a lot of fun with Tektronix 4010 series storage-tube CRT terminals.

In real life they had crisp lines and rarely any perceivable flicker (depended how far you pushed the ray trace line length)

You could drive them (in my experience at least) with a PDP-11, an Apple ][, a BBC micro, or a transputer breadboard.
