- # 'clock' -- A simple alarm clock
-
- # The alarm can be set at 5 minute intervals on a 12 hour basis.
- # It is controlled with the mouse:
- # - Click and drag around the circle to set the alarm.
- # - Click far outside the circle to clear the alarm.
- # - Click near the center to set the alarm at the last time set.
- # The alarm time is indicated by a small triangle just outside the circle,
- # and also by a digital time at the bottom.
- # The indicators disappear when the alarm is not set.
- # When the alarm goes off, it beeps every minute for five minutes,
- # and the clock turns into inverse video.
- # Click or activate the window to turn the ringing off.
