A Flex Shake Effect
When I first got my MacBook Pro one of the first things I did was…type my password incorrectly. When this happens Mac OS provides some great visual feeback with a shaking effect that simultaneously indicates something went wrong and shrugs off the password much like how dogs dry themselves off after a swim. To me, this was very cool. Now, in the great tradition of the web I’m ripping off Apple’s idea to give you a Flex shake effect.
