Of those "walls of air" used to divide spaces, usually to prevent heat or cold loss, or to prevent smoke from travelling? They're high-pressure air shooting down from the ceiling, and commonly encountered in public spaces (I know I've encountered them in some restaurants, grocery stores, and our public transit buildings).

Oh, nothing particular -- just a conversation with marnanel about better and worse ways of handling smoking areas in restaurants and such.
