A exercise in creativity

[nojh]

You open your eyes to a dimly lit room. You are sitting in an armless plastic chair in a room. The wall in front of you is white. Also in front of you is a knee high white plastic table. Sitting on the table is a white box made out of cardboard about one foot in height. Taking further account of the room you are in you notice the room appears perfectly square and the knee high table with its box is in the center. On the wall behind you is the outline of a door cut in the wall, however it lacks a handle or any obvious hinges.

What action do you take?
