If you take your time with the show, there's so many rabbit holes and easter eggs in subreddit discussions. Just search by season and episode like S1E01 or S01E01.

There are no spoilers, but the one I think about all the time is that the creator rendered an image as a sound at the beginning of a really intense episode. The image was the "Hang in There Baby" cat image. A fan's boyfriend was an audio engineer and immediately recognized what the sound was, and processed the audio back into an image.

"There was a strange squiggly noise at the beginning of this episode. My boyfriend is an audio engineer and knew right away that it was the sound of an image being rendered as audio. He grabbed the audio and processed it and found the "Hang in there baby" cat. But what does it mean?"
