This is really cool. I see the demo uses it for CRT stuff but my first thought is this could be used as a tool for accessibility hallway testing to simulate color blindness, haloing (not sure the correct term), and various other visual impairments.

I believe Microsoft already has this built into the OS these days:

Of course shader glass will let you write your own, custom, possibly more-realistic colour blindness simulations, but you don't necessarily need third party tools for that kind of thing these days.

I like to use Sim Daltonism (https://github.com/michelf/sim-daltonism/) for accessibility testing.

Reminds me of cool-retro-term - a terminal that looks like a CRT

Question - How does this capture the entire screen, except its own window?

I've tried making similar functionality in Python to add visual effects to the screen, but the only way I found is to use one of the packages which leverage the Screenshot functionality.

But this causes recursion since my app's window will be in the screenshot (unless I put my app on a different monitor or a different area of the monitor). How do they avoid that?

That's so clever! Plenty of emulators and games don't have native support for these kinds of shaders so just put a filter over it.

Way cooler than Liquid Glass!

I really want all my media players to include this. Cheers doesn't look the same since my 27" CRT died, and watching it through Shader Glass reminds me a lot of the look of that old TV.

Can I change the pixel emulator to something else?

And also, I read it talks to #device capture input (webcam/capture card)#

Can't cheater providers use this to inject colors?

The way I understand it, the shader overlay can only modify what is already being rendered below. It does not have access to the underlying application logic, 3D geometry or other internals of a game that you would need for this. You can increase the contrast etc of a game but you cannot see through walls or anything, so it probably won’t help you cheat.

I wish there were a Monogame plugin that enabled all of these with essentially zero effort.

I also wonder how many could be ported to run in the browser for games.

I need something like this on Linux, any solutions?

I always wish this would also exist on linux.

It'd be cool, but I guess the hodgepodge of different solutions in that space would make it really hard. For example, many mods for GW2 don't work in linux if you're on something like Hyprland due to them having to act as overlays. Not sure if that's a wayland issue or just a typical hyprland thing though

You're right, but a plugin for a common compositor like Plasma's KWin would still make it accessible to a large number of users. Shouldn't be too hard to do either. Maybe I'll do it this weekend!

Awesome! Does it have a degauss button?
