[clug] Countdown Timer

[David (Price) Lattimore]

You could use osd_cat (Debian / Ubuntu package xosd-bin) to display some 
large text on the screen.  Something like the following does a basic 
countdown of how long until 7:30.

while true; do sleep 1; REMAIN=$[ $(date +%s -d '7:30pm') - $(date +%s) 
]; date +%M:%S -d "12am +${REMAIN}seconds"; done | osd_cat -l 1 -f 
'-*-times-bold-r-normal--*-3400-*-*-*-*-*-*'

You'd presumably want to display a black background, but there's plenty 
of things that can do that.
