GLOGSTER

Glogster is a socialnetwork that allows users to create free interactive posters, or glogs. A glog, short for graphical blog, is an interactive multimedia image. It looks like a poster, but readers can interact with the content. The majority of the Glogster community are teenegers

Glogster provides an environment to design interactive posters. The user inserts text, images, photos, audio (MP3), videos, special effects and other elements into their glogs to generate a multimedia online creation. Glogster is based on Adobe Flash elements. Posters can be shared with other users on the site, embedded in external wikis or blogs, and shared via many social networks such as Facebook and Twitter. Glogs can also be exported and saved to computer-compatible formats.
