Another member has a language that is visually based (her species is bioluminescent) and creates meaning based on speed, intensity, rate, color, and position of photophores, combined with body language and possibly a small telepathic component as well.

This post is just bringing out all sorts of language-geek joy in us. Don't suppose you could elucidate a little more on her visual language, do you? That stuff is just all kinds of nifty to us.
