QuarkXPress has hidden aliens. To see one in action, select a page item and press Command-Option-Shift-K (Windows: Ctrl-Alt-Shift-K). An alien will walk onto your page from the right side zap the item off the page. The effect is most fun when the item is near the right side of your display.
Do this 5–12 times to see a bigger alien walk in from the left side of your page and zap the little alien and the item.
