A Proof of Morley's Theorem (from the Devil's book)

In a Temple Seminar (Spring 1995), Don Newman gave a beautiful proof of Morley's trisection theorem that is probably in God's book. However, Satan's worshipers might enjoy the present proof.

Note Added Sept. 9, 1997: Gian-Carlo Rota (``Indiscrete Thoughts'', p. 123) uses Morley's theorem as an example of a theorem whose statement is surprising, but neither its statement, nor any of its known proofs, are beautiful. I disagree. The statement is beautiful, and both Ekhad's and Newman's proofs are gorgeous (in different senses).
