Use of Flickr Mashups or Similar Tools

I think that tools like Flickr mashups could be very useful in a classroom. For me specifically I am going to be a special education teacher working with students with emotional or behavioral disorders, many times these types of students have trouble expressing themselves. Through using tools like Flickr mashups the students could create collages and other projects to express themselves and they could explore different ways to express what they are feeling and thinking more freely. These kinds of tools could also be used to create posters and bulletin boards for the classroom.
