Here’s a handy tip for the day…
If you’re focused on completing a project, or even just watching a movie or playing a game, and don’t want to be disturbed by Mountain Lion’s Notification Center, it’s possible to temporarily disable it.
Option+Click on the Notification Center icon to toggle it on & off.
Just option+click (hold down option and click on the icon with the mouse/trackpad) on the Notification Center icon on the top right of the menu bar to toggle notifications on and off. If the icon is grayed out, notifications are off. If the icon is black, notifications will come on normally.
