Eliminate the annoying vibrating clock in iCal

Everytime I do an update to OS X, I have to run these commands in Terminal, because the animated alarm clock in iCal is just obnoxious. (It also pulls precious CPU cycles.)

Taken from this hint at macosxhints.com, these are instructions for 10.4 Tiger:

cd /Applications/iCal.app/Contents/Resources/iCal\ Helper.app/Contents/Resources/

sudo cp -p alarmclock.mov alarmclock-mov.BAC

sudo echo "" >alarmclock.mov

cd /Applications/iCal.app/Contents/Resources

sudo cp -p alarmclock.mov alarmclock-mov.BAC

sudo echo "" >alarmclock.mov

UPDATE: I posted instructions for 10.5 here at macosxhints.com.
