HTML video and text animations doesnt work together well. No OS X support
now. That is why we could use vlc.

I think no difference between names “changeBackground(image)”,
“showText(text)” and "show_next()" in this case. We can rename functions.

More important to define is it good or not good to use animation between
two frames (divs) instade of animation inside one frame?

HTML-video wont go away - wiht HTML5 it will be just a little bit better
than now.

But HTML5 doesnt solve problem with vlc as background player. Two frames
and separeted control background and content layers can solve it.
