James Choung has released a book and is blogging on his napkin presentation of the Gospel.  In contrast to the Four Laws and the The Bridge, Choung uses four circles to tell the story and provide access to Kingdom theology.  Besides picking up a copy of his book, True Story–A Christianity Worth Believing In, you can explore his website, Tell It Slant, which includes video of the presentation, or you can read the article From Four Laws to Four Circles at Christianity Today.
