iMovie Transition Templates for FCP

I'm looking for video transition templates for FCP like the ones that come with iMovie -- they use art elements to transition from one scene to the next such as movie film strips in which the incoming scene is on the movie film frames. I saw one with Polaroid pictures that fly into the scene with the new scene on the pics. I've searched the net in vain. There are plenty of digital transitions for sale, but none with cool art elements. Anyone know who might sell these?
