Information about Conversion – to bna'i Noach or to Judaism.
You are already a bna'i Noach. All living beings (including Jews) are bna'i Noach. You can go and start following The Seven Laws of Noah right away. This is not an organized religion per-se, however you should join an organization to complete your obligation to create courts of Justice.

Oh yeah, and here's some more videos.
