There a sort of hole in the wall in the hallway by the elevators. It's not quite a hole - more of a cubbyhole about the size of a shoebox standing on end. A couple of cables that the maintenance people need to access run through the hole, but otherwise it's empty. Usually it has a little door on the front that is locked, but the door has been gone for quite a while.

I want to find a small garden gnome stand it in the hole, watching people come and go from the elevators. Just to see what happens.
