>Does someone care to make an ascii?

I hope this helps.  I saw several of these suckers at the show (first time
I've ever seen one, and I finally walked over to find out what they were.)
They're quite silly looking.

Front view:
                          __  
                      ....::   <-- Water goes in here
     Warm           ,' ... ',
     air enters ->  : :###: :
     central hole   '  '''  ''''
     (###)           '..........  <-- Cool air comes out here (through
                                      the top of the passenger window)

Top view:

          There is a screen here covering the hole

     Warm air     :  Air circulates     |
     enters   --> :   around in here.   |  (The back side is sealed)
     here.        :                     |

                         Cool air comes
                         out here
