I love this project! The UI feels so delightful and well thought out. I guess I found another weekend (multi-week?) activity.
If you're looking for hackathon projects, the E-ink ecosystem is well developed enough that they're pretty easy to program against and Claude/the AIs can pick up the API surface. Plus, people generally don't know what they're looking at -- you have to say "kindle-style screen" -- but people (me? but also guests) do seem to prefer having a e-ink screen in the living room over a backlit display because it's so much less intrusive.
FWIW, E-ink [0] AND pomdoros [1] are each a whole thing of mine.
