Because the I pad has 512MB of RAM and your page is 8.5 MB. Fully loaded it looks like >500MB in the browser. It takes for ever to load and it is even slow on my PC with 2GB RAM.
If you want a movie, just make one.
You are asking the browser to load 240 large images (1000 x 700px) Downloading all those resources will take some time. There is little need to dump so much data on the client since large parts of the image do not change at all. Consider deploying movie as movie file or animated gif.
I'm a huge fan of jQuery but jQuery animations are laggy as are. 10MB page of 240 images + the I pad (slower than a computer) = your results In this case mooTools will be better but even then I would expect issues. Images are not intended to be used like this.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
