I am monitoring a competition where each sprint is scheduled to one hour interval. Each team member should have a count down c'lock on the screen, preferrably on terminal. The c'locks should lauch alarm after 45 minutes, 55 minutes and and 60 minutes.
The enviroment should create a feeling of extreme programming. Is there some ready terminal application for the job?
[Clarification] The teams are using Ubuntus and Macs.
Okay, my first question is "good God, why?" How can you do a sprint in an hour.
But having said that -- I presume it some classroom session or something -- there are a number of applications like that; mentioning the operating system might help narrow it down.
On Macs I'm fond of using Miniteur.
On a UNIX system, it's an ur-simple shell script (bash syntax here):
sleep $((45*60)) && echo "Forty five minutes"
sleep $((10*60)) && echo "FIVE MINUTES LEFT"
sleep $((5*60)) && echo 'TIME IS UP!'
