This is another website you could visit for a long time! Gosh, where did the time go? I started out visiting the Matterhorn, then watched sharks feeding in Fiji, and then went on a spring walk in Moscow!
These videos are unique, because while you are viewing, you can shift the video to get a 360 degree panoramic view. Some have narration, some have background music. All have great visuals.
360 photos are available in addition to the videos.
