I have to make a site for a DJ. What cool effects could i add to the site?

I do not have the site uploaded at the moment, but i am working on a DJ’s website. (Known as DJK). He wants something similar to how the effect on http://www.meamusic.com/site.htm works but he doesnt want it exactly like that. He wants some kind of cool background lighting effects and such. I am not quite sure how might do this and make the website still run effectively and smoothly. I will upload the site once i get on my computer at home. Any ideas?
