I used WLED and some WS2811 lights for Halloween this year, and I was blown away but how much it _just worked_. As long as I kept the order of the lights correct (there are arrows, derp), they just strung along. I ended up with a decently complicated array, but as long as my counts were good, the thing just worked. Govee is a very mainstream brand currently using WS2811-based lights, and with a little knife action, you can add them in. I'm hopeful next year to play with some 2D matrix stuff in it.
