Moved feature detection scripts into their own folders and added explict frame_skip value per Ibrahim's request. Finished working on snapshot and video recording scripts for next release. ... From CMUcam4 work I learned that people will just want examples that do "X" thing. So, in general, our examples should include a simple script showing off a feature and then a more complex script that does "X" where "X" is some app that a person would want. For example, we'll get reuqests for face tracking with servos, and movement detection with servos. So, instead of answering this question a million times with an example script we'll just have examples for all kinds of things people will want. Gotta automate dealing with help support at the end of the day...

# recording a Mjpeg file you can use VLC to play it. If you are on Ubuntu then

# the built-in video player will work too.
