A command line based countdown timer gui

(yes, I can slap together something that works, but it's ugly)

COMMAND: countdown_timer <number> <measure of time>

~ countdown_timer 60 m

... and a 60 minute timer pops up and counts down. Maybe turns red and flashes 00:00 when done?

Has sensible defaults (and pref file) and tucks away in a corner always on top. 7 segment LED fonts are awesome.

All the timers I can find and gui monstrosities with hella parameters and button measles.
