Ongs Hat Hoodies

Ong's Hat is one of the earliest Internet-based secret history conspiracy theories. It was created as a piece of collaborative fiction (a.k.a. Incunabula) by four core individuals, dating back to the 1980s, although the membership propagating the tale changed over time. Ong's Hat is often cited as the first ARG on many lists of alternate reality games. The characters were largely based in the ghost town of Ong's Hat, New Jersey, hence the name of the project.

Tales surrounding Ong's Hat suggests it was a clandestine research site. Purportedly, scientists conducted experiments in interdimensional travel there, leading to a secret community's creation in parallel realities.
