Great resource for spotting web pages that have the format you're looking for.

In math, a site that explains things in text is too much like a standard math textbook (yawn!). We need color and diagrams and action. With Search Cube you can see the layout of the pages instead of having to open each one to see if it's a video or cartoons or just text.

Plus, it's fun to watch it build and it's fun to rotate it to see all your choices! Try it for yourself at http://www.search-cube.com
