Video tutorial weblog Tinkernut demonstrates how to create custom screensavers from your own collection of digital photos or videos. You'll need to download a couple of free apps to get started—namely Format Factory and WG-Screensaver Creator—and then it's simply a matter of plugging in the media you want to convert. Granted, most operating systems have a screensaver-from-folder feature for rolling your own photo screensavers, but this method does video and gives you more control over what you see.
