I've heard good things about OpenRGB and I think my keyboard even supports it, but it's one of those "I'll figure it out when I have time" projects.

What really excites me is integration with RGB systems outside of the PC, i.e. room lighting etc. Mostly it just seems to be controlled effects so far, but having a standard for environmental lighting could be (no pun intended) a game-changer.

Imagine playing a horror game where the crackle of surround-sound lighting is accompanied by a real flash from elsewhere in the room. Where when the game lights go out and the red emergency lights come on, so does the room. Etc etc. Yeah it's not going to be for everyone or every situation but if we can get better standardization of supported devices and software integration, it'd still be pretty neat.
