I visited many of the mashup and Flickr tool sites and one of my favorites was The Poster Maker site. I tried my hand at a poster and you can see it below. It was easy and fun, and I think it would be a great way to get kids involved in the classroom. Just as the 23 things blog says, you could use it for many things- I think making a poster that represents novels or part of them, or nonfiction texts would engage students in their learning. I plan to keep playing around with the other sites as well and see what they have to offer!
