Man, my tastes are weird because as much as I LOVE dark mode, I would absolutely rock a theme like this.

A lot of the suggestions in the comments kinda miss the mark... What we want is a very flat 2D-ish theme with over exaggerated shadowing, simple icons, and gentle rounded text areas and windows. None of the elements give the appearance of 3D curves or crevices. They remind me more of stickers.

One thing that bugs me with that mockup (and sorry because you won't be able to unsee it) is the inconsistency in shadows - some buttons have it, some don't. Some icons have it, some don't.

It is otherwise a really clean and nice layout. I dig the retro warm vibes.

Has anyone not mentioned Openbox yet? Window decorations look like the NeXT style, just colourful.

I don't know of a specific theme in the neubrutalism/neobrutalism style (names that are generally used to describe this style or aesthetic), but it shouldn't be too hard to make.

For anyone unfamiliar it's generally defined by flat, blocky layouts, with thick borders, single color drop shadows and a few bold high contrast colors (think CGA and EGA monitors if you're that old). It often features “unpolished” elements like flat simple shapes. Bold fonts and monospace fonts are pretty common.

There are a few resources out there if anyone wants to play around with this style.

I want this so bad. Although in practice I imagine none of this will fit together well with the YouTube interface or with a custom desktop background.

HomerOS here we come

Neubrutalism?

I was developing a widget toolkit that implements neubrutalsim but it's defunct now... Fuck life

Possibly easier achieved with a window manager than a desktop.

It reminds me of bOS.

Paper GTK theme is a little bit similar, though with more vibrant colours ofc.

Maybe not all that close, but it's the best I can think of right now.

I think it has the general old school vibe, maybe you could tweak the colors to be a bit brighter like your example?

I really dig this aesthetic, man. I think it's time to learn how to build a theme.

XFCE looks closest shape-wise. it also has the advantage that you can customise it using css.

while not exactly what you're looking for, DesktopPal97 may be worth looking into as a base for your own theme.

It almost looks like an old BeOS theme maybe? This Haiku one for GTK isn't too far off, so maybe you can start with this and alter it how you like: https://github.com/B00merang-Project/Haiku

Where did you got this image from? Knowing its origin could help find the source of the theme, if it is at all an existing theme.

It looks like the kind of interface they’d use in classic Pokemon or Stardew Valley. I like the colours.

Interesting idea of icons and windows sharing the same plane...

I'd suppose if you ask this on KDE Reddit someone with enough time could make something like this with Kvantvm, though the difficult parts would be (1) the web browser theme, and specially (2) the icon theme - I have never ever seen an icon theme like that for Linux
