This is a new thing that I've been trying recently, 360º Video. I've been shooting lots of it, but this is the first time that I've tried embedding it into my website.
On a desktop you should be able to click and drag the picture to move the image on any direction. On smartphones it may recognise the gyroscope and let you move the phone to move the image.
The video is also on https://gallery.giroptic.com/play/SgjIe7JCzOYf6 if you find it difficult to play back here.
