What's the significance of the dots?

This is Bruce Schneier's wedding ring? Awesome. Talk about being consistent. How does the crypto-ring work?

No, MY ring -- Bruce designed it. Stay tuned for details, shortly.

Oh! I had the same question about whether these rings were yours or belonged to Bruce. How exciting!

It seems like the most obvious encoding would be:
top dot = advance this letter
no dot = no change
bottom dot = go back one letter.
But that actually destroys information if two different letters in the plain text can code for the same cypher letter. Hmmm...

Ok, I think I got it.
The dots are arrows. There are 6 different ways they could code.
Top Dot, No Dot, Bottom Dot. Each codes for a different ring slice. Left, middle, or right.
For encoding to cyper text you start with three letters and the rings are alligned to that permutation (676 of those). Each plain text letter starts on the left and depending on the dot is swapped for one of the three letters on that line.
-
This is especially nice since a plain letter can code to it's cyper letter and totally throws off statisical attacks.
ooOOOoo, and if you changed the three letter alignment regularly it would be even harder to crack. Ah:
1 - start with 3 letters
2 - code first 3 plain text
3 - use resulting 3 letters to realign rings, or use plain text letters.
4 - repete until done.
And if the number of swapping letters on the line was varied too, that'd be tough. The number of steps a plain letter takes to the cypher letter.

Am I close? I'm sure I've missed a bit or two.

I can't help noticing that there are three statuses (dot above, no dot, dot below), and three wheels. So, I'm guessing that since 3 x 3 x 3 = 27, that three characters with statuses are used to code for each one character of unencoded text.

So, for example, A is represented by - dot above, dot above, dot above. B is represented by - no dot, dot above, dot above. And so on.

There is one combination of statuses unused (no dot, no dot, no dot), which I'm guessing corresponds to a space.

Looking forward to further details...!

Good number-eye MykReeve.
The dots are regular.
The top alphabet cycles 123-123-123...
The middle 112233-112233...
and the bottom 111222333...
(Which gives us a partial set in a regular permutation and implies another 3^78 (1.6x10^37) different cypher rings of irregular permutations or only 27! (10^28) regular ring sets)
If there was a 27th letter of the alphabet the dots would be (going from the top alphabet down): bottom dot, no dot, bottom dot. 323
