Wow, this takes me back! I remember visiting pages like this in the early 90's while rendering fractals in Fractint. I remember following a bunch of Geocities pages that looked at Pink Floyd's The Division Bell album, and there being a hidden meaning. Turned out to be created by the record company, but as a high schooler on the early internet, I was fascinated with it.
