Put your Webcam to good use..

The webcam that came packaged with your computer system can do a whole
lot more than just let you video chat. With the right tools, you can
turn your webcam into a watchful surveillance tool, a face
recognition-enabled computer login utility, a time-lapse movie-maker,
and more. Let's take a look at some ways you can get more out of your
underutilized webcam.

Video chat alone is worth the cost of a webcam, but
your webcam is capable of so much more than that. Let's take a look at
a few more obscure but very worthwhile alternative uses.

Turn Your Webcam into a Motion-Sensing Security Camera

Apart from video chat, the coolest thing you can do with your webcam is
turn it into a surveillance camera. If you're a Windows user, several
free tools are available to help you do just that. The best option of
the bunch is probably the Windows-only Yawcam (original post).
Yawcam does motion-sensing with very little setup, then automatically
backs up surveillance images via FTP or email. Alternately, there's the
open-source Dorgem (original post) and web service HomeCamera (original post).
Each tool has a slightly different feature set, but between the three
of them you're bound to find the features you want from your security
webcam.
Linux users can get the motion-sensing goods with the open-source app Motion, and if you're nuts for Twitter, you could try setting up your webcam to send a Twitter notification with your motion-sensing webcam.

Login to Windows with Your Face

Freeware application LemonScreen (original post)
adds face recognition to your Windows login screen, allowing you to login to your locked PC by simply sitting down in front of your computer. It's not foolproof by any means, but it's unquestionably cool.
