At a cafe today I saw a wonderful collection of antique jack in the boxes.  It occurs to me that these could be used instead of a traditional baby monitor.  (of course, the aiosphere cannot be used for mission-critical or safety-critical systems).  I’d probably build them such that they can both launch and reset themselves.  They would pair with a device at the baby, perhaps a stuffed animal, that would detect the baby’s waking and trigger the popup and music downstairs.  The parent could then go upstairs, calm the baby, then push a button on the stuffed animal to reset it.  Or, perhaps it automatically resets when the baby quiets.  If a user intervention is required, it should be something more subtle than a button.  Turn the animal’s head or something?
