This site is full of interesting information on world religions and associated material. Navigate to more goodies from the menu on the l/h side or go to the top level domain.
One interesting article on the site discusses the famous "crystal skulls". One theory posited in the article is that the use of quartz means the skulls are somehow programmable.
I'm not sure how serious this site is in its content although there is sufficient factual info' on comparative religion to make it a useful research tool.
Have fun.
