One of the RPi project pages shows a simple stop-motion project using the Pi camera:

The new High Quality pi camera is more interesting to me for this use than the previous pi cams, because of the variety of available C/CS lenses with manual adjustments for focus, aperture etc. The one thing I haven't seen is a program that provides the "onion skin" function that most smartphone stop-motion apps have, where the previous captured frame is overlaid with (for example) 50% transparency on the live view. Is this something anyone has tried before, if it is possible?
Thinking about it, in this case you don't necessarily need a high framerate, or max resolution on the live view. So I guess you could just take a series of stills MJPEG style, and combine the images on the CPU without needing real alpha-compositing on live video preview from the GPU side.
