I found two interesting tools/applications when I was reading David's Technology Tidbits: Thoughts of a Cyber Hero. The first one is 5 Card Flickr . You randomly get 5 pictures that can then be made into a story. Further ideas can be explored at Lesson 42 at Interface Magazine.
The other is an educators search engine called Topic Box. I found some very interesting link from the UK using this search engine. Education is changing from the inside out as we connect to each other around the world and share information, insights, as well as frustrations.
