I made an icon set (.icl) for CataclysmDDA using the original .ico file that’s used for game’s executive file. I did only some minor changes, so whenever (and I think it’s all the time) you’ve got multiple builds at the same time you use for different characters or features (or just versions if you wish) you can pick one of ten icons in this set.
The reason I didn’t go with .dll is mainly because I cannot know if everyone’s Linux instalation can handle what’s inside them. The .icl (the Library) is definitely a feature I’ve only seen in Windows XP and beyond, but it’s still viewable from an Editor.
It’s made with freeware software. Support open-source and no-cost endeavors!
Because of the transparency feature found with .ICO format, the cataicon_lib is suited for darker backgrounds; I didn’t work my way through layers for the original icon file, so if you’re in the mood for some Zs over black bg, you’ve got the game.
Enjoy!
