This is charming. E-paper is such a good fit for ambient data like this — always visible, no glow, basically no power. How often do you refresh the display, and does partial refresh ghosting become a problem over time?
This resonates with me. I recently built a community site (user submissions, votes, comments, Google login) as a plain static page on free hosting, with a hosted Postgres behind it. No app, no server of my own. People assume you need an app or at least a backend for anything interactive, but the modern web platform covers far more than most product teams give it credit for. The whole thing costs me $11/year for the domain.
