Facebook is rolling out its new Say Thanks feature, the new feature allows users to create personalized video cards for their friends with just a few clicks. The best part is, all one needs to do is to pick a theme and select which memories (photos and posts from Timeline) they want to be used in the video, once previewed the user simply clicks the "share" button and the final video gets posted on their timeline with friend getting automatically tagged and the video showing up on his or her timeline.
