Showing a Delayed Webcam Image I have a Logitech USB webcam, and need to display the image from it on a second monitor, delayed roughly 15 seconds ish. How would I do this?
I'd try VLC in Terminal:

/Applications/VLC.app/Contents/MacOS/VLC qtcapture://


Ask on their forums. If there isn't an option to delay the direct display, you can always "stream" it to another VLC process and let it buffer for 15 seconds.
