Where can I find a stop motion Camera?

I won't recommend a stop motion camera. I would recommend software however. If you have a video camera then record a frame or two and pause and keep repeating until you finished it. If you have a digital camera, just take a photo for each frames and put it all into something like windows movie maker and edit it there. Or get a webcam for about $30 and use some software such as Anasazi (Windows) or Frame by Frame (Mac) both are free.
