Lately I have been playing around with a fun little application called Smoovie, which pretty much allows you to take as many photos as you want and puts them together to create stop motion movies. I've been taking photos with my MacBook webcam and a remote so that I don't risk knocking the camera ever so slightly and I'm quietly pleased with the results I've been getting.
The main models of my silent films so far have been Fisher Price toys- with the star of the show often being a little blue Batman. They've gotten gradually longer as I've experimented with different camera angles and frame speeds (Smoovie allows you to manage the frames per second- or fps- of your pictures between 1 and 30fps).
