Maybe I'm just tired, but I'm having a hard time figuring out how to start playing after I create an account.

Has promise, just needs some tweaks.

I would try to make it 'less sensitive' when transitioning, so the user doesn't accidentally switch images.

Also there needs to be a way to tell that there is a layer of images. Maybe some relative positioning on the ones that are hidden?

Cool idea though.

Too bad Firefox really sucks with it.
