The Plinko Floor compresses slightly under each person standing on it, allowing balls to roll under individuals and indicate their presence. I created it to subtly acknowledge other people in an elevator space, a place where we often actively ignore others and attempt to blend ourselves into the background.
When placed in a public elevator, there was a high barrier to entry unless an actor was used to initially engage people. After engagement, when two or more people were on the floor, they got closer to one another than they would have normally. The interactivity of the floor causes them to ignore their previous personal space boundaries and break the rules, or cultural memes, associated with elevators.
