I need photoshop help (making an image spin)

Alright, so I’ve re-jailbroken my iphone, and I put video wallpaper back on it, however I found an awesome image that I thought would look cool as video turning, so I decided to make it.

After a lot of cutting, pasting, erasing and filling in gaps, I have an image that while rough on the edges, if you make a layer with a gap in the middle that is the iphone 4s screen resolution, it can turn smoothly and look perfect (I’m quite proud that I was able tog et it to work actually).

However, I need some way to turn this image into a video of it rotating, but only showing the area that will be the background. I was thinking of doing it with a GIF and converting it to video, I have before, but this would be a lot of rotating, and since the image isn’t uniform I have to set the center each time which is unreliable. Arbitrary rotate would work if it uses the center but It’s roating the whole thing.

Someone please help me figure this out, here is the PSD, I’m at a dead end with this.

If there woulkd be a way to get the stupid target to be in the middle it would be fine, but its always off center even if I make the canvas perfectly quare.
