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 a 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.
