QTVR is a format developed by Apple for viewing panoramic images as a 360 degree "virtual" movie. You can scroll the image up and down, left and right in the viewing window by dragging with the cursor. You can zoom in by pressing the "Shift" key and zoom out by pressing the "Ctrl" key. Each panorama has both large (about 2 meg) and small (about 600K) versions.
You must have Quicktime 4 to view.
