I am trying to find a tutorial that might help me achieve a sliding gallery. What I want to do is have a row of thumbnail buttons across the screen, and when one is clicked the whole row slides so that the one clicked moves to the center and then the fullsize appears over it. Also want the row of thumbnails to "wrap around" to the other side of the screen when it moves out of the screen.

I am sure there have been tutorials on something similar but everything i have searched for brings up everything but the type of effect i am looking for. ANy suggestions?
