I'm new in this, and I find it very interesting. I've read the discussion and I have to agree with Zack Leven in the part of if we're trying to figure out the meaning of any message with a human-like point of view we're going no where. But the representation of using letter for identifing the diferent 'tones' (frequencies) detected as part of the message is well and does suit into the problem. The only thing I care about right now ( and before spending more time in it ). Is this real, or only a joke?. If it is real, where can I confirm this information? Why I haven't heard about anything related with this messages in news, magazines, etc?
