I wanted to have something containing "three" because I got three characters now. I also believe that number won't increase anytime soon (though if it does, then I'll be fine with it, too).
So I tried different arrangements until I had one I liked. And there's one more reading for this one that's surprisingly fitting and relevant: it resembles the pattern you get with the double-slit experiment which demonstrates that light and matter behave like both waves and particles. A happy coincidence.
