I was working on 81 today and came up with something interesting. I did a google search: ascii -character -art -hex etc. and came up with Amsterdam Subversive Center for Information Interchange. Kept digging and came up with ascii (squat) which led me to ascii squat symbol. There is an International Squat Symbol which is a CircleN.
This sounded just bizarre enough for the devs. However I don't know where to take this and I know both Viv and hvsavage are excellent researchers. Maybe someone could follow this. I tried many things I found in the articles and got no CBNC.
