Recently I covered the draft code to add a full VR mode into the KDE Plasma desktop, and it has only continued to get more advanced with recent updates.
The developer, Stanislav Aleksandrov, also updated the draft to very clearly note "I do not work for Valve, this is done in my free time", before people jump too much about anything here being related to the upcoming Steam Frame it's unrelated.
A reminder on what it does from the draft merge request:
This plugin turns KWin (and KDE) into a 3D VR Desktop. Features:
- Floating windows
- Physical and Virtual screens
- Everything is 3D, even wayland surfaces, window decorations and shadows
- Made for work: Full keyboard control
- Headgaze: no mouse, touchpad or vr controller is required
- Native Qt rendering: direct dmabuf imports.
- Follow Mode

On January 24th, Aleksandrov noted in a comment that two needed patches in the Qt project were approved, but one is still to go. On top of that some more major features have been added to it now including:
- Improved Follow Mode: now it tries to move all windows to bring the closest window to your view if outside of configured FOV until it reaches smaller stop FOV. This feature somewhat starts to conflict with 'Grab All' and 'Recenter': you can now continue to move your head to position all windows where you want them to be.
- Headgaze setup: the new configuration page to setup Head Ray with preview. You can interactively choose starting position and rotation of the Ray and its colors.
- Lock Screen: All windows will be hidden when the session is locked, except the lockscreen(s) and lockscreen overlays in the same way as kwin hides them.
- VR Controller bindings: now the plugin loads XrInputAction(s) that are really needed
- Reworked InputSetup page: it is split for 4 tabs now and looks a bit better than total crap -_-
Would love to see this eventually be accepted, would be pretty amazing to try out on a VR kit. Makes me think of what Apple attempted with the Apple Vision Pro but doesn't cost multiple thousands.
I'm convinced that Compiz was why Microsoft launched that abomination, Vista, with it's exceedingly Emerald-like "glass theme" and a very familiar looking alt-tab animation!
Anyway, this project gives me the vibe. Obviously, it'll be less impactful, needing a VR headset to work, but it's still just incredibly sci-fi. I love it.
(p.s. I still use wobbly windows today, although the fire effect has been replaced by the "old tv turning off" effect, and I don't need a cube anymore, cos 4K screen mean I only need two surfaces. but it's still cool!)
Quoting: scaineCompiz ... Wobbly Windows, spinning cubes, fires consuming windows, genie effects when minimising. It was awesome.
Not sure about the other effects, but the first one is available on GNOME,
[Compiz windows effect - GNOME Shell Extensions](https://extensions.gnome.org/extension/3210/compiz-windows-effect)
OR,
[Compiz Fusion - GTK Window Decorator](https://www.compiz-fusion.org/wiki_subdomain/decorators/gtkwindowdecorator.html)
And on Cinnamon,
[Extensions : Wobbly Windows : Cinnamon Spices](https://cinnamon-spices.linuxmint.com/extensions/view/83)
And on KDE Plasma,
[Compiz Fusion - KDE Window Decorator](https://www.compiz-fusion.org/wiki_subdomain/decorators/kdewindowdecorator.html)
There also appear to be numerous attempts to mod that effect into M$ Windows too ...
