There is an Ong’s Hat section in this French article, from the site Tryangle about starting your own religion, titled: TUTORIAL: HOW TO CREATE YOUR OWN RELIGION?
Excerpt (machine translation):
In fact we can find the origin ARGs “occult” or “sacred”, in particular through the myth of Ong’s Hat . In the 90s indeed circulated anonymous documents, Incunabula Papers, which told the story of a team of physicists, refugees in the ghost town of Ong’s Hat, which had succeeded in using tantric techniques to contact parallel universes. But this story myth, far from being presented in a linear fashion, as in a novel, was distributed over multiple independent media, browsing els networks (which at the time consisted mainly of small telephone servers because the Internet was still very accessible to the average person) or available via fax or photocopies … Especially at no time said document does not explicitly claimed as fictions. The game designer Denny Unger shows in the passage that follows the religious aspect, occult, the myth of Ong’s Hat:
Ong’s hat and Incunabula have always treated the problem of levels of understanding. When you look at every aspect of the story, you find yourself facing a challenge. You discover an exciting info that takes you on a path only to discover that it was a dead end, but … he is ultimately the way you thought wrong is the right truth, and so on .
A portion of the population simply does not grasp the incunabula and will be a “weird thing” but some will be captured by them, obsessed with their mystery. This obsession usually lasts until the person has extract of the story something that is vital for it. There is also another kind of explorer incunabula. This one goes beyond personal obsessions and begins to understand a more comprehensive picture by linking information apparently unconnected. What it perceives is also a series of carefully constructed to filter certain types of personalities and find suitable “candidate” tests. A general scheme of Incunabula appears. It reminds initiations sects, but is very different because this process selects a particular type of personality someone hedonistic, open-minded, but skeptical, with a free turn of scientific spirit, creative, thinker, educated, and critical. Certainly not typical of the standard sect initiated.
