How about a timer (for example when you have to change the laundry) that flashes (and sounds) when the time is up. You can also add a mode that displays the amount of time remaining until the timer is expired (or until your alarm goes off).
You could add event memory for multiple alarms (with one-time, daily, weekly events, etc.) and timers.
Also, you can chime (or sound) the hour (and special tones for half and quarter hours).
Since it is electronic you can add a tick-tock sound (like a grandfather clock) to give it that good old calming sound. (Make the volume adjustable though.)
