Reverse Alarm Clock
A researcher at Carnegie Mellon University, John Zimmerman, has developed a clock meant to keep children in bed, rather than wake them up. Children often have an abundance of energy that allows them to wake up early, disturbing parents still trying to sleep; the Reverse Alarm Clock calculates moonset and sunrise, and uses this information for some simple symbology. When the clock's moon is lit, children are expected to stay in bed. When the moon is off, they are allowed to get up, but should avoid making any noise. Finally, the sun indicator shows that children must get up, which is helped by wakeup music picked earlier by the children themselves. Music can also be set for going to sleep. Unfortunately for parents, there are no current plans for a retail clock.
