One of the keys to the site, says Internet Explorer's Roger Capriotti, is software developed by Bing called the Panorama Viewer. "We've taken David's great imagery, converted it into website code, and then the Panorama Viewer gives us the ability to pinch and zoom and get into incredible detail."
Structured around a trek from the Nepalese village of Lukla, home to the Tenzing-Hillary Airport and the start of most Everest expeditions, to the very top of the mountain, the site is a series of stunning gigapixel and high-resolution panoramas which, when zoomed into, reveal surprising secrets.
A beautiful view of the Khumbu Glacier stitched together, says Capriati, from 457 high-resolution images, yields seemingly hundreds of brightly-colored tents of the Everest Base Camp. Scroll up and zoom in again, and there are mountaineers beginning the long trek up the mountain.
The more you zoom in, the more Easter egg-like surprises reveal themselves: a horse by a tree in a monastery, for example, or a video of a bazaar. Although it functions across all platforms, the site's full impact can truly be felt on touch screen-enabled browsers and devices: mouse clicks work just fine, but these are images that yearn to be scrolled, pinched and zoomed.
