I’m in a state of the art movie theater. The screen is three stories high. The patrons sit in swivel chairs, like Captain Kirk’s, on several broad tiers, each rising above the one in front. Confusingly for me, every chair has a little screen mounted on its right arm, for watching the movie or (presumably) something else.
Also, why should it be a swivel chair? Does it mean that I’m supposed to face a different direction?
I pivot about 120⁰ to the left, away from the big screen, until I am facing the aisle and the door in the left rear corner. Now I can see if my friends are coming. While I wait for them, I can also watch the movie on the little arm-mounted screen.
