One of my sons is a language nerd who learns grammar rules for fun. Not only does he study a bunch of languages, living and dead, ranging from Sanskrit to Japanese, he also designs his very own weirdo language, featuring his own weirdo script system.

I haven't been able to fathom what kind of satisfaction such a pointless exercise could possibly get him, but now I guess he'll have the last laugh when he dumps another Voynich manuscript on the world!
