This is a little model of the Hatch from the TV show LOST. If you are a diehard fan of the show (as my whole family is), you will recognize the scene. If not, then the Hatch was an underground room accidentally found by plane crash survivors on an uncharted, mystical island somewhere in the south Pacific. Here, they have opened up the Hatch, and are peering down it for the first time.
I received this model from my son as a surprise gift, and it sits on my computer desk.
