Macworld's Dan Frakes shows off his favourite screensavers for Mac OS X in this video clip and many (but not all) are free, including AlphaBabySaver, Big Time Screen Saver, Econ, and Euphoria. Hit the Macworld site to get the full list of recommended 'savers. Personally I'm a huge fan of the built-in Word of the Day 'saver on my Mac. Do you use screensavers any more? Which is your favourite? Let us know in the comments.
