What a cool thread!
My ds6 used to write a lot of lovely stories, which ended after he started school and got miserable. But two days ago, reading the book Dragonology, he noticed the key to dragon runes, taught himself them - all but Z, which is hard b/c you never use it, Mom - and suddenly began writing again, just in Dragon! He's got pages of story about a dragon who goes to a Red Sox game, which he then gleefully asks me to read, which I can't do, b/c *I* can't read dragon. And even better, his teacher let him do it yesterday after he finished his work, so he came home happy from school for the first time this year.
And the same day, ds3 did a 96 piece puzzle, and ds8weeks used a consonant for the first time and said "bleh!" it was a banner day.
