The website for Fantastical, a smart menu bar calendar utility for the Mac, uses some clever animation to draw your attention to its interface and features.

Clicking the “Removable panel off” link on Apple’s product page for the redesigned Mac mini will cause the bottom panel to subtly rotate, as if you had to remove it in the real world, then disappear.

The Reeder for Mac site leverages some impressive HTML animation tricks.

Update: Thanks to Brett Taylor for this one: just like on a Mac, you can Shift-click to experience the animation transitions at roughly half speed.
