Every UI must look good in B&W!

So this is rebound of basically the most popular dribbble shot. Decided that I'd give it a look in my portfolio style, which idea is to give everything black and white look, but at the same time my works are colored to give them more attention.

I do understand that this probably cannot be used in any real web-site, but despite that I create my interfaces with an idea that every UI must look good even b&w.

"L" would be much appreciated!
