In an elevator or a restroom stall. You must to stay to interact. Isolated or even singular. The work plays on a screen in front of you while you are in the stall or elevator. You would have to stay to watch it and it would be randomized so you may not see the same thing as others. Would you stay? Would you feel awkward? Come back to try again? Would it matter to you? If it were a narrative, it would make you realize you were supposed to stay. If it made you uncomfortable like what if it were made to look like a cctv of someone else going to the restroom? If it were one thing at first and then something else, like ads or lovely photo reel but then after time, it suddenly changed as if a secret transmission?
