Okay, I think that the site is, at least in part, the work of a form of schizophrenia.
There's a certain similarity in the way that the site is constructed to the way that schizophrenics see the world, as well as the way that some of the text is written. The artwork, however, is the thing that has the most obvious hallmarks of the schizophrenic.
Compare this picture:

With this one, by schizophreniuc artist
Glen Brady:
Two things to note are the way that objects are bisected by lines - the forms break up somewhat, which mirrors the way that schizophrenics percieve the world visually. Also, note the way that the figures in the paintings are looking at you. In fact, Brady's work is somewhat atypical for a schizophrenic in this regard, as the eyes are usually more penetrating and larger, more like the one on the site. You can see more stylistic similarities with regards to the eyes in this pic from the site:
See
this page for an exploration of artist Louis Wain's work, first before he had any mental illness, and subsequently as his schizophrenia progressed. Note the eyes of the cats, as well as the interruption of their solid form which gets more progressive as the illness progresses.
Compare the stage 4 or 5 cat to this picture from the site:

And that's pretty much it as far as my theories go. The dissassociative nature of schizophrenia and the loss of ability to distinguish between fantasy and reality (at laest as much as in a mentally healthy person), as well as the styalistic similaritys to writings and paintings done by schizophrenics evident in the site certainly seems to me to be indicative that that's at least a reasonable explaination.
FWIW, I've had very, very brief online interaction with the Rob Bell, guy who actually put up the site, and he has said that he's not schizophrenic. However he is, in his own words, "just the webmaster". The guy who was actually responsible for creating the site is David Denison, and Mr. Bell didn't say whether he was schizophrenic one way or the other.
[Edited to add]As well as the religions and things mentioned, there's also some of Crowley's work and some ideas used in freemasonry in there.
