I like this one for all the art, but don't see myself spending a day in bed with the gray walls. The guest rooms dark (is that black?) walls just beg for a lot of frames on it.

I like this new take on such a thing that has been well known for so long. P.S. His name's spelled Mondriaan...

I saw them use it on posters and such for concerts for example here. You could take a picture with your mobile and order tickets if you have the web on it.
