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.
