Use whatever you like or how you like it, modify and take parts from the config files, I personally don't care (that's how we start ricing anyways). And I'm not that well organized, so some of my dotfiles may seem a bit weird on the config files but when I have some time I'll definitely make the code pretty and easier to read. And these dotfiles are kinda old too, I'm not that much into customization anymore since I become a vanilla KDE Plasma user whe I started to use Gentoo.
I've used i3-gaps, that's my go-to tiling wm, along with polybar and picom for transparency, but this time I just used a lighter color from my wallpaper because picom was turned off. Here's the unixporn reddit link. For the dotfiles, check here. I also have used an ascii art generator for the void linux supremacy text, here you go.
For this one, i3-gaps as well, cmus, nano, pfetch, nothing really special. That was one of the first rices I did. You can follow the reddit post link right here where I've put some info about it, and the dotfiles on github repo right here.
I loved that one, it's not technically an rice but i've put some effort to make it working. As I don't have the dotfiles for it, you can check the xfwm4 theme and the r/unixporn thread here. there's instructions on how to install and get it working there. IndigoMagic for XFCE and unixporn thread.
Nothing too fancy, just some pretty colors and a nice wallpaper. r/unixporn reddit post link
