I, for one, would be thrilled never to see another boring PowerPoint presentation as long as I live. Especially one where the presenter gives you a paper copy in advance (thanks for the handout, and now can I leave?). I've heard about Prezi but never seen it in action until now. Check out this presentation by Elisabeth Harris, Decatur branch Youth Services librarian (and Paideia parent).
I can't take the class (it's for teens aged 13-17), but I will definitely be exploring the possibilities of this software. PowerPoint, beware!
