Heirloom Box
Heirloom Box - This box is a self-locking capsule for personal relics, designed to be bequeathed and inherited. Once it is closed, the object is locked inside for many years. During this time, the box counts down to the moment it will reopen. When touched, the number of seconds remaining is displayed on an LCD through a two-way mirror. The box relies on its current owner to stay powered -- it must be shaken once a month in order to charge by magnetic induction.
