Blue-hued 3D manatees and fish roll, float, and swim in stylized rippling waters. Erie MP3 music plays in the background. Sound can be muted. Images are 3D-modeled animated GIFs. Password protection is available for your OS X system screensaver (so once your screensaver kicks in a password is needed to get back to the desktop, which protects your computer from prying eyes while you're away). It supports dual monitors.
