FLIF can also encode animations. This page uses APNG images, if you browser does not support that, the images will not move. Consider the following animation from the Mozilla Animated PNG demo page:

Just like with static images, animated FLIF files can be decoded progressively: the entire animation can be shown (at a lower quality) before the entire file is downloaded.
