I don't have a webcam on my desktop computer but seeing as how I can connect my phone to my computer, and my phone has a camera, I'm wondering if there is an easy way to use it as a webcam? Obviously I'd need some sort of dock to keep it aimed the right direction, but I'm looking more for the technical details.

I've got a Windows 7 Desktop. Not sure of the actual computer/tower brand- it's something custom I got from NewEgg a few years back but I doubt that makes a difference. It should be plenty powerful in terms of hardware requirements.
