I'm curious if this has ever been asked before.

I know that this may not be a valuable asset to anyone else, but I'm wondering if it may be possible, if there is an app that does it, or if one can be created.

I'm sure you all know how webcams work. You plug it into your computer, and then you can broadcast video over the net, record video and save it to your hard drive, take photos, etc. Well, my question is, simply, can the iPhone act as a webcam?

Thanks in advance for your input, and respectful responses.
