Startup screen

Up to OS 9, the Japanese versions of Mac OS used to display the words "ake-mashite omede-tou gozai-masu" (that means "happy New Year", see the left photo below) on the startup screen on Jan 1. This "Easter egg" had lost on OSX, although you could see it on the splash screen of "classic" OS9. Mac OS10.5 does not support classic mode; however, alternatively you can see the word "ake-mashite omede-tou" on the screen of the screensaver "Word of the Day" on Jan 1 if you set the default language in Japanese (日本語) (see the right photo).
