I think I called them nits. trits would be 3-ary, akin to ternary.

 Since you do a lot graphics programming, have you ever thought
about encrypting images with XOR?

Indeed.

I just did a small test with
my xorpng program and wrote a message for you with my little
WACOM tablet and Microsoft Paint. :-)
 I think this is a really cool (but then with a mouse instead
of a tablet) when traveling and exchanging keys in advance with
family and friends and using a Bitmessage's alt.anonymous.messages
chan and my p4bm program, in case Computers are compromised at the
destination, when not carrying one and you need no credentials and
only the keys on a Kanguru Defender 3000.
 Here are the test images:
 https://jmp.sh/jp1A5kvq
 and here is my xorpng and p4bm program:

https://github.com/706f6c6c7578/p4bm
 

I am sure you are familiar with tux:

We can encrypt that image in many different ways, indeed.
