I'm still just trying to get my terminal to look like the Portal (1) Aperture Science screensaver, but for some reason last time I tried I couldn't get it just right. Now that I have KDE (and thus color picker and Konsole), I should try again..
The hardest part is the glow effect on the text I think.
This is more like Fallout than Portal but maybe it can work for you.

I've never been more excited about ruining my eyes π€©
I used the thing here a while back to take a screenshot of running gopher on some of the remaining gopher servers in gopherspace (note that the sdf.org guys shown here also run an lemmy server, nicely linking the past and today). Its default settings in amber were a not-wildly-unreasonable match for some of the VT terminals connected to a VAX/VMS system that I used in the 1990s. More noise added by default, but it's the closest thing I've seen to a replica to that era that one's likely to see short of getting an actual CRT VT terminal and plonking it on your serial port (well, these days, probably a USB-to-serial adapter).
EDIT: Apparently this guy set up docker images on Debian to emulate old computing environments and then rigged that to a VT420 and ran gopher on that:
Hahaha, been there. :)
It can do bloom with its shaders, the way @[email protected] wants. I don't know if any of the presets have quite that much bloom, though.
It can do CRT-style scanlines, as he's looking for, and it doesn't have doesn't have to have the faux-CRT curvature; see the "Futuristic" preset for a preset that doesn't have that curvature.
EDIT: There's a settings dialog that lets one ramp up or down each of the given visual effects.

Though this seems to have multiple of those "falling" bright areas, and cool-retro-term only has one. I'm not sure what that's supposed to be, for either the screensaver or cool-retro-term. You can get a vaguely-similar effect if you have a video camera taking footage of a CRT; I guess the proper term for this is the stroboscopic effect. Might be what they're trying to depict.
Thank you! I had no idea what "bloom" was (clearly, because I called it glow lmao).
This is at least close enough, if not perfect, especially if I can (and I expect so) change the background to the aperture logo (which can easily be found in the correct orange/brownish color online).
You cannot in the current mainline branch, but it looks like someone has a pull request open for the past couple months to add a background image.

Ayy alright! Here's hoping, thanks!
If I remember right, they were adjustable in its settings. But it's been a long time since I've used this.
You're right...just checked, updated my comment, and then saw yours. :-)
Huh, cool! Apparently the dev who made this thought about everything. :)
One eye-candy thing it can't do is animated cursor movement. Not sure how to describe this, but basically, when the cursor moves, you draw a trail behind it.

According to that, KiTTY got support for it six months ago.
EDIT: That being said, that's not really "retro", so might be out-of-scope for the project.
