Please take a look at htttp://ckdisco.com/ for the layout of the website. The site itself features translucent "blocks" of content over the background, so you can partially see the background through them - "opacity" may be a more familiar term to you, though I do not know what percentage.
If you view the background (http://ckdisco.com/wp-content/theme…ray/bg.jpg), the only requirements I really have are to include a design for the menu bar across the top, and for the bottom to fade into a solid color. Feel free to use the entire space and be as creative as you like. What I envision is more detail towards the top and the sides - I would also like to see "faded" designs in the middle, where the "blocks" of content will be laying over them.
Other than that, some ideas/concepts you could try integrating are a web 2.0 discoball, a watermark of the SAE Crest (http://files.sae.net:86/images/symb…e_Coat.jpg), and "1979".
There is also an image for the bottom footer (http://ckdisco.com/wp-content/theme…footer.gif). I am planning to extend the height of this image to at least 150px, so I would like something that fades into a solid color at the bottom if I decide to extend it even more.
My fav color is blue, and my 2nd is orange, though I don't know if I like the two together. You can go with a neutral black/white/gray, or even try combining all of the colors together... Feel free to be creative and try what you feel is best.
Here are a few examples of the design styles that I like:
As you can see, I like the "cartoon" type style.
