Ah, thats the one. Couldn't remember where I saw it or what it was called.

I like the youtube one I just found (out of guilt) as you see the prop starting.

 

[shower another shower]

don't they all look like that?

 

[Goodbye]

No.

Its called Image Aliasing. The chip in the iPhone cant keep up with the speed and writes its own new image.

Many people, who have tried taking a picture of a spinning airplane propeller with their cellphone cameras, have been surprised by the outcome. After all, they didnt expect to see many ghostly propeller blades floating in the air without being totally detached to the airplane.

What happens when a slow scanning digital camera (like the ones on many cellphone) captures an image, it does not expose all the pixels at the same time. Rather, it exposes and captures one row of the sensor and then moves on to the next row. This video explains what goes on in slow motion.
