The homepage does not contain information about the criteria that are applied by the Twitter screensaver. The screensaver will display an image once it gets turned on. The major part of the screen is reserved for the image while a smaller strip on the bottom is reserved for the name of the Twitter user and the message send by that user.

Images are rotated every 30 seconds automatically. This basically means that a new image and message are displayed every 30 seconds while the Twitter screensaver is running. The screensaver requires an Internet connection to pull the data from Twitter.

The major drawback of Twitsaver is that it does not offer customizations. It is not possible to change the frequency or specify certain Twitter users that should be used exclusively.
