Just in case a bouncing icon in your dock or a Sosumi sound from your speakers isn’t enough to catch your attention, this OS X accessibility feature is certain to be just the news flash you need when OS X demands your attention.

Enabling ‘screen flash’ in the Accessibility panel in System Preferences adds an extra layer of alertness to a busy environment by displaying a lighting fast flash across your screen, similar to what you see when snapping a shot in Photo Booth.

You can test out the screen flash before enabling the feature, and personally I found the experience to be quite jarring, but it  certainly can be a handy accessibility feature and could be a useful tool for your workflow.

You can also do similar on the iPhone: Settings > General > Accessibility > LED Flash for Alerts.
