Thinglink it a neat little web tool for collecting resources. You start with a picture - maybe a map, science experiments, or computer parts. Once your picture is uploaded, then you can begin "tagging" areas of your picture with resources like websites and videos. I can just see teachers with interactive whiteboards going from resource to resource at the front of the room with this tool. And I think that the placement of the tags on an image is much more effective/attractive than just a collection of links on a Word doc or Power Point. Below is a sample that I threw together for our GA Studies teachers; hover over the image to see the tags and click to open them.
