Dynamic content is what I am going to use for my thematic online photo gallery. It basically means a website that regular updates it’s content, there are many examples of this on the web. Since dynamic content can include text, images, sound and video I can show examples of each different version.
It has been used here by YouTube to create a personal experience of videos that you may be interested in based upon history and likes;
It is also used to produce results to a user specified search term such as “uptown funk bruno mars”;
