If it counts, I'd just say: this website. I've rebuilt it so many times over the years, and each time it's a really fun opportunity to learn new things, try new tools, refactor things with new knowledge and better abstractions, and just...play. So: while I just finished rebuilding this current iteration of my site, I'm still excited about my backlog of ideas and things to try next.
Maybe in a year's worth of iterations things will feel quite different here.
