#64 looks very scandinavian (for those who might not be aware - codeaid is Danish - Denmark is in Scandinavia). This logo will be applicable in many different media, but for some reason (even though the symbol is pretty nice and has a nice flow) it's hard to get the meaning. It is supposed to be letters, right?
I did not know its actually scandinavian for this trademark. I just want to have a very simple and clean logo which its why I created this out. Let me know if you are keen to see more changes, and yes its A & C combine together.
