Fireflies
Not on the coding side, but the inspiration. . . For those of us in the USA, there is a much more accessible version of synchronous fireflies at Great Smoky Mountains National Park in Tennessee. I lived there for a few years and went multiple times[1].The dates get announced a month or so beforehand, and tickets are based on a lottery system since it only[2] occurs on one side of one river for less than a mile. You can technically also hike in if you're ok with 8 or so miles near sunset and then the same amount out in the pitch black. I believe that is frowned upon, but very few people do it that way (I was the only one the year I couldn't get tickets and decided to hike).[1] https://www.flickr.com/photos/23215983@N02/albums/7215764507...[2] Not exactly only, but certainly the most strongly.
