public art form

For idea, I want to explore the social norms people expect to see happen in public, and what happens when they aren't done, namely when someone does something that's just not the norm.

I had the idea that 4 or 5 people would each go to an elevator around campus, preferably buildings with several elevators. We'd wait until the car had only 1 or 2 people going in it, then we'd enter like normally. But once the lift doors close, the 4 or 5 people turn around and just face the 1 or 2 people. The idea is when this happens, it can be extremely uncomfortable for some inexplicable reason. People naturally expect everyone to face forward, and when even one person does it, it can be a little weird. The rules are as follows:

1) No touching of the people.
2) Act as if nothing were out of the ordinary.
3) Make minimal interaction with the people. Maybe a "hi" or other one word responses, but no more.
