I recently rediscovered this amazing website. Be sure you use the
controls (left, right, up, down) after choosing a photo:

Note #1. For photos where there are no controls, just right click and
move the cursor.
Note #2: there are many additional categories of panoramas available.
Check out the beautiful shots of the Grand Canyon.
