While I've been out and about, I've been mentally spec'ing out the Chumby Mastodon client. Given the platform's limitations (320x240 screen, no web browser, 350 MHz processor), I've come to the conclusion that I'll have to do most of the work on a server and have the Flash UI serve as a thin client.
With no good means to talk to a modern mobile device, I'm thinking about integrating QR codes as the "read more" mechanism for expanding toots, opening URLs, and sharing.
Rough current to-do list:
* (Server) Implement client registration and user authentication mechanisms.
* Decide which Mastodon features make it to the Chumby (favorite, boost), and which get left out (replying).
* Implement server that publishes a private feed (to-investigate: Flash Basic HTTP auth support)
* 320x240 UI design. (to-investigate: small pixel fonts)
For the UI design, I'm starting to get some ideas from these gaming console-based CSS styles for the Web:
