how's that sound... using your mobile camera as your webcam..That to with no additional hardwares ; surprised well its true.. All you need to convert your mobile cam to a webcam are
- Cell phone with java, Bluetooth and camera in it.
- Bluetooth adapter for desktop
- computer
- a software which converts your mobile cam to a webcam.

Run smart cam program in windows. And open smart cam in your cell phone as well.
In windows, choose Bluetooth as the connection in Files>settings.
In mobile... you can select connect and choose the pc ...but you should note that your PC must be visible to everyone in order to detect the PC by cell phone.
