Have you ever seen Steve Jobs (or anyone else) do the "slow Genie" effect when minimizing a window on Mac OS X, and wondered how they did that?
Turns out it's pretty simple: just hold down the Shift key when clicking the yellow minimize button on any Mac OS X window. Assuming you have the Genie effect enabled (see your Dock preferences), the Genie effect will still work, but it will send your window to the Dock very slowly. This may not be too useful for everyday work, but it is kinda cool for presentations. :)
