I love, love, love Lomography and the fun plastic cameras that create such individual photos.
One of my faves is the Action Sampler camera that comes with multiple shutters the fire off sequentially. I use it a lot.
It works best with motion, making what can best be described as a four frame movie (or more frames depending on which camera you have. They go up to 9 shutters).
So of *course* someone created an iPhone app that does the same thing, making the camera fire off shots one after the other then bringing them together in one photo. It's called QuadCamera.
Check out today's trip across the Golden Gate. iPhone held out the window as we passed under the south tower on a nice sunny day. (straight off the camera, no adjustments done)
