[ale] Linux countdown / egg timer app?

[Christopher Bergeron]

Does anyone know of a good and simple egg timer / stopwatch like app for 
linux?  I'd like to be able to open a program that will let me specify 
"5" minutes and count down and pop and alarm sound, or popup or 
something after that time has passed.

Also, I'm looking for a GUI app, not cron or at.  ;)  I'm on Fedora Core 
3, with Gnome desktop.

Historically, I had been using Cooltimer for Windows, but I'm using 
Linux as my desktop machine now and I'm seeking a replacement.

Any ideas?

Thanks,
CB
