Create a theme based on all video games

I need a theme background for our website. This theme will be about everything games, from old school nintendo, sega, to xbox, to wii, to ps3, and so on. This collection of picture graphics will be the main background on our website. The image will repeat vertically and horizontally because its going to display on an HTML base, and not in CSS style. So this image needs to wrap around graphics from top to bottom and from left to right. There will be no focus point for any one graphic because the home page consists of a wide header, close blocks on left, story pages in the middle, close blocks on the right side, and a wide footer. I will give you the URL so you can see what you are working with.
