chicken.js

(function(word) {
	var walk=document.createTreeWalker(document.body,NodeFilter.SHOW_TEXT,null,false), el;
	word=word.split("");
	while(el=walk.nextNode()) {
		el.nodeValue = el.nodeValue.replace(/\w+/g, function (o) { 
			return word.map(function (v, i) {
				return (o[i] < "a") ? v.toUpperCase() : v;
			}).join("");
		});
	}
})("hodor");

It's a fork, yo. I just made it so the word stuff is easier to change.

yeah but dat formatting doe

also you're re upper casing it for every letter
