Recently I found Taggalaxy, an amazing Flickr searching web tool that creates a visually stunning way to explore images. Taggalaxy puts your search into the metaphor of a planet, with connecting ideas and themes as smaller planets around it.
When you click on a planet it collects images from Flickr with your tag, and allows you to browse and zoom through hundreds of pictures. Brilliant in the classroom for an inspiration board, or as a discussion starter. I used this last week when asking children to create mood boards on Ancient Egypt, worked perfectly and had the children captivated. It really has to bee seen to be believed.
