That’s awesome. I took this a bit further a few years ago making a url only notepad quine that as you add data to it, creates itself. that can be saved as a bookmarklet. Have to watch the gif to understand
I saw one before that was doing this and saved the whole thing as a base64 stream. So the url would dynamically update and have all its data. Pretty cool. I suppose the main obstacle is now where do I load the site from, and how much can be stored in itself or an image :)
