Problems in iPhone 4s and iPad 2 explorers

I am a newbie here so I do not kow how to ask

Learning Edge Animator and Muse I delvoloped a simple site and a simple animation, both works great in Windows 7 & 8 PC explorers (MS IE, Chrome and Safari for sure).

But on iPod and IPone (safari or chrome) the animation never ends. (I do not have a mac, yet)

The site is here

http://pegece.com

In order to isolate the problem I had tried the the animation alone  (meaning that the problem is not Muse)

The size (pixels) seems to be the problem

Any help, advise or tip will be appeciated...

Regards
