Zoom.it is a new web service introduced by Microosft Live Labs team. Basically, you let it know the URL of an image and Zoom.it will let you experience a smooth span and zoom of the image.
It is kinda cool and you’ll be able to share the URL to your friends afterwards. As cool as this sounds, it works only if you feed it a high resolution image (obviously). If not, you will not be able to zoom further or start looking at the horrible pixels.
