I always liked some of the things that were done
as part of the "Tempest" overlay
http://en.wikipedia.org/wiki/Tempest_%28codename%29
From simply recording typewriter keystrike sounds to this,
makes you wonder what really is going on that is
still unpublished.
Funny how its all useless if just one whistleblower puts it
onto a usb stick :shrug:
