If I may intrude, the Internet is filled with charlatans creating subliminal content. Some use "Free" Audacity and Nyquist filters to build and hide complex subliminal messages in music, recording TV and more. Try a movie weekend, with a few plausible friends. Have various subliminal chants, embedded in movies, CDs and birds tweeting, calling you the Übermensch, and describing why. See what happens and report it here.
