Flying around the desert, your cabin will fill up with flies on the ground. The little window is a great way of getting rid of the flies. All you need is a short length of flexible hose. Put one end of the hose out the window, and use the other end like a vacuum cleaner. Chase the flies around the dashboard, and as they get close to the end of the hose, sluuuurp! They're gone!
My vote for the most original use of the DV window goes to this one!
