Still working on it. And I'll probably release it down the road, when we get ready to maybe tie "Zodiac" to Manson and Son of Sam. For now, keep this in mind: "Zodiac" moved heaven and earth to get the 408 and 340 published in the papers. But NONE of the other cryptograms. He didn't care on way or the other. And by the time of the map code, the handprinting and other features pretty cleary show someone else had taken over writing the letters. So, it's THEIR map code, whoever they were. And they never intended it for public consumption. Only for someone at the Chronicle, and mmmaaayyyybeee law enforcement.
