Pattern Clock is an alarm clock that can not be turned off until the sleeper can repeat back a randomly generated pattern of flashing lights.  

Many people have no idea of what being late means when they first reach over to turn off their clocks.  And as you become familiar with an alarm clock, you actually learn to turn them off in your sleep!    

Pattern clock eliminates this by generating a new pattern that you must be awake to memorize and repeat.
