The mysterious sign on the door

Some time in the future, people going out to the movies will slip on a comfortable lightweight pair of glasses. Through those glasses they will be able to have experiences far beyond the capability of today’s movies.

Stories will take place all around and between people, as though the entire audience has become transported to another world. The rectangular frame that we now associate with visual storytelling will come to seem quaint.
