Related to knight rider there are a few guys out there making a KITT simulator. Now we all know that Ultra Hal can be made to look like KITT and its probably way better than this simulator but what got my attention (which is why I am posting it here) apparently this CAN use a web cam as an EYE in what they called surveillance mode.
This is a snip of there site:
About the surveillance mode:
There will be a motion detection, so if you have a webcam, KITT can also SEE what's going on, and if there is
something weird happening KITT wil ask who's there... And takes a picture.
If no one answers, KITT will record a video.
When you're back, you can look back at the Video
and you can see who the intruder was!
This is the web address
