Craigp, (edited ) I love when people create astounding works of art but they're in such hilariously tiny niches that nobody will ever know.
I consider speedruns like this, but also things like people spending weeks remixing a let's player.
Of course it happens all over. I'm sure if I was into knitting, I'd see knitting masterpieces.
I just love knowing that people will spend thousands of hours on what they love, even though it will never leave the tiny group of people it was intended for.
