thanks for the info, I'll have a look at how it works on weather.com and if I can grab the image.
About updating, it normally updates every hour, but you can change that easily bu editing the script and change the value at line 109 by the desired time between updates (in 1000th of seconds)
About the other stuff, if that info is in the RSS feed it is possible to display it. Cycling the system tray icon is not really something I wanted (I preferred something simple and discrete), but have a look at this program: http://code.google.com/p/eeeweather/
It has more features than mine, maybe you'll like it too.
