Website header background

I am looking for a sleek looking background header. The header will be on my site [[login to view URL]][1] The logo you see in the?middle is allready done "**Bilverdy VFX**", but the rest came with the CMS template which another person made for me and l. The thing is, that the site will be a video effect tutorial site, and NOT a music site which the current background looks like now. I am inspired by [login to view URL] So I need a nice background header with something that will relate to video effects, tutorials, compositing and so on and it should blend with my logo and the website layout. Come up with some ideas or better yet some mock shots.
