Raining/Rolling Image Transition

I was looking for a very specific type of transition and ccLeaf already has it but its locked with an existing transition that I dont want. Please make a rolling image transition that takes up the entire screen without the rain. You can make it its own transition by making it 3D and have it kinda roll over if you get what i mean.
