Magnoto is a new (beta) site that is similar to Glogster. It is designed to create an interactive wall/web page. The user interface is fairly simple as you can drag/drop all of your multi-media content wherever you like.
For this to be a real eye-opener for educational, it would need a specific instance such as Glogster. This way teachers could monitor and create user accounts for students. However, that being said due to the simplistic design I recommend giving Magnoto a look.
