Sensors are not as trivial a film. At least for me the simplicity of chemistry was always simpler than the magic of electronics.
Vimeo user Raymond Siri created two quick, yet informative animations for Canon that illustrate how CCD and CMOS sensors work.
The movies show how the light is filtered accumulated and then they show the difference in how the data is sent for storage.

The movie illustrates why CMOS sensors are prone to Jello or Rolling Shutter effect. The CMOS sensors sends the image line by line, so there is a lag between the time the first “line” is scanned and the time the last “line” is scanned.
Here are my own animations that explain how this impacts the final image. (I have to say that they are not as fancy)
