Shourov has created an interesting mashup at Search Cube where you can navigate Google search results inside a 3D cube. Search Cubes shows thumbnail previews of up to ninety-six websites, videos and images fetched from Google using your search query.
These thumbnails are arranged on the wall of a hollow cube that you can rotate or flip using the mouse and arrow keys. To view details about a particular search result, just hover your mouse over the corresponding thumbnail. Thanks Kristian Still.
