I'm aware that there used to be a Chroma integration for League of Legends, but it seems to have been abandoned.
The plan is to eventually add support (animations) for as many game events as possible, including ability casts from all champions (Vel'Koz and Ahri are in place right now), and active item casts (wards, zhonyas...).
The following features are implemented as of today:
- Health Bar
- Animations for Champions
- Out of Mana warnings
- Summoner Spell casts
- Animation on Kill, or Death
Contributions are very welcome! You can see the repository and suggest changes here: https://github.com/nicolasdeory/leagueoflegends-led .
Many champion animations have yet to be implemented, so any help is welcome!
