Build a little diffuser dome (with "clear" PLA) that attaches to a base with a mount for a small addressable LED ring. It's all 5v and low enough consumption you can drive it straight off the MCU board. I flashed it with WLED and can run a ton of different lighting effects. Even hooked it up to homeassistant so I can do all kinds of smart home integrations. Great as a little accent light or just to play with smart home automation.
