I have seen many implementation of the page peel effect. I have seen then written in flash which I am not very fond of and some written so bad that it can crash your browser. Here is a article on a simple way to make one using jquery and css. You can view a demo of the peel effect here. I haven’t had any issues with the demo for the peel effect on any of my computers including my linux machine, which is more then can be said for most peel effects I have seen.
