Cooliris
Cooliris, formerly Piclens, has been around for some time now but is suddenly gaining momentum. The 3D display of images on a wall is now being adopted by many library collections as a way to not only showcase but search for materials. The power of this tool comes from what can be displayed along with the image (i.e. title, artist, date, description and other related fields). If we can leverage the power of embedded metadata along with Cooliris it will be a new and exciting future for collection search and display tools.
