Zoom.it is an innovative technology develope by Microsoft Live Lab to help bloggers and content publisher share high resolution images and web sites. It’ll convert your website or image into Deep Zoom format, and use SilverLight component for fluid zooming. Microsoft acquired Seadragon for it’s zooming technology in 2006 and had since use it to power Pivot and Photosynth.
