Everybody can (and should) try this with their phone camera.

Just put it in Panorama mode and move the camera in non-standard ways.

Like this it will work on passing trains. It will also (kind of) work out the window of a train.

works out the window of a car too. It will get confused and "compress" parts of the panorama.

It will also work vertically...

It works on tall trees - scan with the arrow from the base upwards to the top.

You can also make weird photos vertically if you keep going. Start from in front of you, up over your head and facing backwards.

Also fun is to try is facing down to the ground and walking forwards. You can get a garden path or the sidewalk or other fun panoramas. If you want, you can intentionally stick your feet in the frame and get "footsteps" along the panorama.
