Having only just acquired the link from Gordon who was late when he posted it, I'm even later for the first annual CSS Naked Day. I've had a quick look at the site with the stylesheet links commented out (I didn't check that there was no CSS in the markup itself, but there probably won't be) and I'm pleasantly surprised; Nucleus pulls through again...

I'm not going to subject you to unconditionally to the site's naked glory, but unfortunately it won't let me put raw PHP into the skin files so I'm probably not going to bother doing it conditionally either. You'll just have to wait until next year.
