Clock provides visual cues on appropriate sleep/wake times

We’ve previously covered persistent alarm clocks, but never appreciated the need to address a complimentary problem: people who wake up early and don’t realize that others in their household still need to sleep. Now there’s the Stoplight Alarm Clock, which flashes red at “appropriate” sleeping times and green at customary wake-up times. Could be useful for some folks with autism or other cognitive disabilities.
