Haha, see GitHub. I think this is pretty cool but I want to clean it up a bit -- for example, the feed query will select stories related to you currently (e.g., someone updated a revision you are a reviewer for) not just your activity, and the calculation of hours uses server time when it should use the user's local time. Raphael also has enough weird glitchy things that I'm tempted to try d3.js. I'll see if I can do a pass on this once I get a chance.
