I can't help but think that the NSA would have taken the letter more seriously if had been typed.

"I'm not a crank. Here's a diagram of my machine." {Blue and red line everywhere}.
It seems he considered how a handwritten letter might be perceived.
In all seriousness, this pdf basically unreadable. It would be nice if there was a readable version available to the general public. If there is one, please let me know because this is very interesting.
I'm not sure if my pdf reader confused things or the nsa has a special redirect for me. But the complete handwritten text is perfectly readable to me now. I'm not sure what I saw before, but it was odd...
