Power Macintosh Easter Egg -- Mike Basham <firstname.lastname@example.org> has reported the first Easter Egg for the Power Macintoshes. First, make sure no debugger is loaded. Hold down the interrupt switch while turning on the Power Mac, and then let up. The Power Mac will crash, accompanied by some, shall we say, realistic sound effects, complete with breaking glass.
Better Text Formatting in iPhoto
If you're creating a card or book in iPhoto, and you're not happy with the formatting options for the text (such as line spacing or justification), copy the text out to TextEdit, make the changes you want there, and paste it back into iPhoto, which will retain your changes.
