Background design style similar to Vimeo.com / Twitter

I need a background design that's similar in style to [login to view URL] & [login to view URL] (Twitter, when logged in - you see the clouds). I have a website that is a coupon/deal site and would like the background bottom of the site like [login to view URL] and the top to be like Vimeo and/or [login to view URL] Please show me more example sites like [login to view URL] to get some ideas. I have seen them but forgot their URLs. I'll need to see your example works and mockup of concept to make a final decision. Please have fun with it since you're the artist, I don't want to limit your creativity scope. Something that involves shopping would be nice. Thanks! Please message me if you have any questions.
