I make holiday light shows with an open source program called XLights[0]. I'm sure you've seen the videos[1] of what people[2] can do. Usually the top comment is "man that is cool but I wouldn't want to be their neighbor!" followed by "my neighbors love my light shows".

Creating the sequences is time consuming, and lot of people end up buying them or sharing them, but those are rarely as good as the ones you make for yourself.

Some folks have dabbled with using AI to create the sequences. I think the biggest issues are lack of training data and it's a very visual art, so there needs to be a better feedback between the text representation and the visual manifestation.

So if you're into using AI to make physical world things better, that would be a good place to look!
