Cycle through the weather options in dashboard!
A great tip submitted by Peter Czosek: Cycle through the weather options in dashboard! It is more a fun tip than a productivity tip but it looks very cool in front of your friends who use PC. In dashboard, you just have to press "Command-Option" and click anywhere on the weather widget (the one included with the OS). The city will switch to "Nowhere" and if you continue to hold "Command-Option" and keep on clicking, you'll cycle through all the possible weather conditions. There are a lot! If you leave the dashboard and reopen it, the widget should come back to your original city. Thanks for the tip Peter!
