Even the states of the ternary computation seem to be up for grabs [1]. My first feeling was that the balanced ternary states would be nice, but as you start building trytes (i.e numbers) the representation doesn't seem great.
I couldn't find anything after a very quick search, but if not already done, I want to start referring a ternary bit as a 'tit'!
