Search google for wearable computers - I remember seeing a wearable at
the Linux Bier Wanderung in Coniston back in 2000, with a bash prompt on
a 20x2 LCD display.

Re switching to a terminal when you plug a keyboard in, how about
running screen on the device? That way you can switch between the clock
process and whatever else you want at a keystroke or two. The only
problem I can see is that it won't automagically switch back to the
clock, but you might be able to hack screen to do this.
