Anyone considering things like that should also be familiar with the "Styx on a Brick" work, where the Vita Nuova guys stuck a Styx interface on a Lego mindstorm controller brick. The interface layering from the raw serial interface up through something which you wrote times to (and the clickable GUI on top of that) remains a really great illustration.
