Well, you can't easily change the actual image that's being used, unless you maybe use Javascript, so if you want to make it larger with css, it'll be blurry. Making it smaller should be about an hour's work, maybe less, but I'm not bored enough to attempt it now - and CSS3 means only modern browsers would support it.
