Nifty applescript "alarm clock" I use with iCal... Inspired, adapted and mostly stolen from my buddy Jason Deraleau on #opendarwin [irc.freenode.net]

-- launch iTunes and start music slowly increasing volume
set volume 5
try
	tell application "iTunes"
		activate
		play playlist "easy"
		set i to 10
		repeat 100 times 
			set the sound volume to i 
			set i to i + 1 
			delay 0.25
		end repeat 
	end tell 
on error 
	beep 
end try

 

Thanks again Jason
