Theme Design Similar to Airbnb

Hi,

I’m new to WordPress so please forgive any ignorance that I may be showing..

But I am looking for a theme that is similar to the Airbnb website (www.airbnb.com) where there is a large background photo that changes each time someone lands on the page (I know this can be controlled via a script). The user should be able to browse through a few photos as well.

On top of this giant background image, I just want a simple registration box to overlay in one of the corners of the page, similar to how airbnb has the search fields setup. This could either be an email capture to notify when the site is live, or a facebook connect login to register. Since this will just be a splash page at first, I am only concerned with users registering/submitting email.

I also want people to be able to “like” “tweet” or “pin” that background particular image.

Does anyone know of a good theme that will get me close to this and then a few plugins that will help out with the registration field and social media components? I know I’ll have to do some tinkering myself, but if anything comes to mind that is readily available, it would be much appreciated.

Thanks!
