I'm always on the look out for interesting web-based apps that can be used on a Smart Board. While Bookr doesn't qualify as an app exactly, it's a fun way for a teacher or teacher-librarian to create content for primary kids, and even allow older kids to develop their own material. (And it's great fun to use a Smart Board or LCD projector to show it to the class.
Taking images from Flickr, the user assembles a multi-page, digitally flippable mini book. Tell a story, illustrate a poem, make an ABC book... be creative!

The final product can be shown from a "bookr" page or embedded onto a class website or blog. Lots of fun.

Ans here's a brief video demo:
