Excellent article.<p>I remember a few years back holding my mobile to the window to take a photo of the scenery while on a turbo prop passenger aircraft. I nearly had a heart attack when I noticed the propeller had stopped spinning!<p>Once I got over the initial shock and realised it was just rolling shutter on the phone screen I had a bunch of fun taking photos and videos of the effect in action. I&#x27;ll try and dig up one of the videos and post it here later.
