You can now simply build your output from a simple key/val dictionary
including the weather icon buy pointing to your icon set or change
to download from Yahoo. Also, grab the radar if you want one.  

To run in Geektool, open shell and add: python /path/to/your/weather.py 

Don't forget the change the paths to the image files below.
