Nice, simple little program. Functions seamlessly. While there are other, more dynamic alarm apps. most, to my knowledge, sit either in the Dock or on the desktop. This one sits, unobtrusively, in the menubar. An earlier review mentioned Growl! integration. Mmm...not sure that's necessary really. Set this to repeat mode; that should provide sufficient, repetitive visual stimulus, particularly as it's accompanied with the sound alarm also.
