Do y'all remember the little thing that evil people would use to keep the seat in front of them from leaning back? It was put on the tray table leg and was banned by the airlines since it might tear up the tray table.

Well, I've wanted to invent a space divider that would slip over the armrest, essentially giving ALL of the armrest to the person next to me, but creating a mini "wall" between me and the next person that would keep their arms and butt from getting into my portion of the seat. I could wedge myself into this space just fine.

Let's face it, few things are more revolting than the prolonged touch of a stranger.
