The Buddha Garden on "Responsive Themes That Are WIDER Than 960 On A Desktop?"

Hi everyone;

Are there responsive themes out there that are WIDER than 960PX when viewed on a desktop, but will slim down on mobile devices?

With 21 inch and bigger monitors becoming more prevalent on desktop machines, it seems silly to have your site on a tiny portion of the center of the screen.

But the only responsive themes I have seen are all 960px wide on a desktop.

thanks in advance.
