I’d gone cough many years and never heard of 1-Wire and, suddenly, it’s everywhere.

Addressable LEDs are hugely popular in tinkerer circles. Addressable LEDs come in myriad forms (wheels, matrices) but commonly they’re sold as long strips. The part number is WS2812 and they use 1-Wire too. Each, often multi-color (RGB) LED (often known as a pixel), is combined with an IC that enables the “addressable” behavior.
