For anyone turned off by the CoffeeScriptiness of the page, here's a bookmarklet that will compile the CoffeeScript into JavaScript:

  javascript:(function(e,a,g,h,f,c,b,d)%7Bif(!(f=e.jQuery)%7C%7Cg%3Ef.fn.jquery%7C%7Ch(f))%7Bc=a.createElement(%22script%22);c.type=%22text/javascript%22;c.src=%22http://ajax.googleapis.com/ajax/libs/jquery/%22+g+%22/jquery.min.js%22;c.onload=c.onreadystatechange=function()%7Bif(!b&&(!(d=this.readyState)%7C%7Cd==%22loaded%22%7C%7Cd==%22complete%22))%7Bh((f=e.jQuery).noConflict(1),b=1);f(c).remove()%7D%7D;a.documentElement.childNodes%5B0%5D.appendChild(c)%7D%7D)(window,document,%221.6.1%22,function($,L)%7B$.getScript(%22http://cdnjs.cloudflare.com/ajax/libs/coffee-script/1.2.0/coffee-script.min.js%22,function()%7Bvar%20a;a=$(%22code.coffeescript%22);a.each(function()%7Bvar%20a;a=$(this).text();return%20$(this).text(CoffeeScript.compile(a,%7Bbare:!0%7D))%7D);return%20a.each(function()%7Breturn%20prettyPrint(this)%7D)%7D);%7D);

Aside from CoffeeScript's __hasProp and __extends boilerplate at the top of each code sample, it's pretty readable if anyone's interested.

I still think it ought to decide whether it wants to be a CoffeeScript or JavaScript framework, though.
