It is actually pretty easy to see air moving, either directly by injecting 
smoke or mist (glycol works reasonably well, aka disco waft) or indirectly 
via phase optics.  The latter method can even determine the actual 
temperature since the function of density vs. temperature is known.  You've 
probably seen air move above asphalt on a hot summer day with your naked 
eye.  That's the same thing, just with a less sensitive measurement.
