That's called 'art'. It's someone's self-expression that you connect to. I can't speak for the author, but that's how I look at my experience of engaging with, and especially of creating, such projects.
It's art, in the medium and using the tools the author knows. Many associate art with certain mediums, like paint on canvas. But does the painter make a sculpture or build the perfect engine? The programmer, when they feel the drive to make art, makes a program.
(Another signal of art, IMHO, is the author's seeming disinterest in global adulation. They aren't aiming for virality or influencer status or the next startup with an exit, not pivoting to the trending thing; they are making what they love.)

But again, I can't speak for this author at all.
