Thanks Luke. I'm stumped about how affine transforms could account for these effects, particularly bubble, pinch & swirl. Also, iiuc, UIImagePickerController doesn't give access to the camera input stream -- just an image when the user actually takes a picture. There's a new takePicture method, but I don't think it can be called frequently.
