As for a symbol or gesture I can see why you use 1 and 2. However to me the representation of 1 and 0 is more sound.
1 is the individual
0 is the whole
This might be a little more esoteric but it resonates within me at a level that is less language and more symbolism.
What comes to mind here then is the power symbol.
The first one is more symmetric and less suggestive of a phallus I think. It could also stand for awakening as an allegory of power off or on.
It's simple and it's widely recognised, maybe readjusting it's meaning is possible and even as a process better than something entirely new?
I'm not sure.
However one could easily transcribe this into a gesture.
(Deaf gesture for G, which in less shorthand for is the power symbol laid sideways.)
One other thing that I do without noticing it half of the times is the Prana mudra in front of my nose. If someone can shed light on this I'd be quite glad to hear it by the way.
It seems like a splitting of the eyes, as if I acknowledge to recognise this for what they are, but it also is a I on an O, a straight finger before a face.
