How he did this?

hi, i would like to know how this little site is built?

http://www.aniline.se/

I think its not just 1 swf file there must be more because if i visit the site once more you dont have to load the pics you have seen before.

I’m also interested in the mouse effekt (the + and -) and the preloader

Hope someone can/want help me

cheers
Tom
