This seems like a really good concept to keep in mind. I wonder if it could be applied to other fields? Could you make a pot that remains a pot the whole way through, even as you refine it and add detail? Could you write a song that starts off very simple but still pretty, and then gradually layer on the complexity?

Your post inspired me to try this with writing, so thank you. :) We could start with a one-sentence story: "Once upon a time, two lovers overcame vicious prejudice to be together."

And that could be expanded into a one-paragraph story: "Chanon had known all her life that the blue-haired Northerners were hated enemies, never to be trusted, that she had to keep her red-haired Southern bloodline pure or the world would be overrun by the blue barbarians. But everything was thrown in her face when she met Jasper - his hair was blue, but he was a true crimson-heart, as the saying went. She tried to find every excuse to hate him, but time and time again Jasper showed himself to be a man of honor and integrity, and when he rescued her from those lowlife highway robbers - how could she not fall in love? Her father hated it of course, but even she was shocked at how easily he disowned her, how casually he threw away the bonds of family for the chains of prejudice. She wasn't happy now, homeless and adrift, but she knew that she could never be happy again in the land she had once called home. Chanon and Jasper set out to unknown lands in the East, where hopefully they could find some acceptance and love for their purple family."

This could be turned into a one page story, and then a five page story, and so on, never losing the essence of the message. Iterative storytelling might be kind of fun for people who are trying to get into writing something long but don't know if they can stick it out for months or years.
