I wondered how you make one, and I googled, and the advice was to use the Google Streetview App.
So I had a go - here is the video
This is what the image looks like flat!
And this is what it looks like on Facebook
P.S. Yes, that video, I know. I should have pointed it so I was in the middle, and should not have had auto focus, especially when the microphone was sat on the camera and pics up the focus motor noise. It was done badly and I was buggered if I was going to do all that again. I hope it conveys the message though...
