This post could also have been titled: "how to lose family and friends quickly with your iSight-enabled
Mac." A poster over at macosxhints discovered that you can start a
new video recording session in QuickTime Pro on an iSight-enabled Mac (for that low-profile surveillance look), and
invoke Fast User Switching while the QT Pro session keeps on recording. For more stealth surveillance, you can set your
display to shut off and, aside from the green light, most people will be none the wiser.
exclamations of 'how dare you?!' aside, I wonder if this 'built-in webcam' feature is going to inspire a new niche of
unique video recording software.
