Advice/Suggestion/Idea Background Img Needed For Blog

Hi !

I am currently Designing a WordPress Blog, and have become unable to come-up with a idea in respect to a cool graphic for the it's background.

The Blog is an Afrocentric/Urban motif, with the purpose of attracting-catering to African Americans and people of color. But all people are welcome to enjoy my Blog as well. I'm just saying !

What I want is perhaps something Urban in style, something that won't strain or burn the retina. Maybe a Brick Wall, with some modifications within Photoshop. I don't want any City Skyline or people, just something simple and neat.

If maybe anyone has any ideas, I am open to suggestions.

Thank you....
