To date, I have gathered up about 40 GHz worth of computing horsepower working around the clock in an attempt to brute-force crack Z340Q3 (Zodiac 340, Quadrant 3). Grand total, i've generated about 14 billion keys so far, and perhaps predictably so, I have not yeilded anything solid.. A few provocative misses, but nothing above instances of 3 four-letter words.. something which could be chalked up to "monkeys at typewriters generating Shakespeare" sort of stuff.
(For the curious, read below. A few days ago, one match came back with "wait bus bomb", which seemed tantalizing since the Zodiac killer referred repeatedly to blowing up schoolbuses full of kids... However, the match proved to be just a randomly generated fluke.)
Anyway, I had a novel idea while working on the latest incarnation of code.. Why not give it away on Reddit, and see what happens?
So, here it is:
Of course it's gibberish. The previous code was cracked in less than 24 hours, and according to FBI profilers this pissed him off quite a bit. The natural thing for someone with a need to be superior would be to make something uncrackable... so either it's gibberish or it's based on something that only he could possibly crack (eg each symbol and it's x-y coordinates corresponds to a character, page, and line from a book that only he knows of) and thus might as well be gibberish. An interesting thought though is if this code gave him enough fame/entertainment in an area besides murder so that he stopped killing.

Hey guys, I responded to the author but no response yet. I got a hit. But a little background. I edited the script to include the zodiacAlphabet into the regular alphabet and also added slices of the original encryption (5 characters long each) as words to look for as hits.
I received the following hit.. please help me understand.. did I just find 3 instances of 3 slices of its own "encryption?"
