Haha, that's almost me too ^^ - today and yesterday pretty much.
I just uploaded about 6 files. If you're looking for conventional, with some sane example code, see this one. If you're looking for craziness, there's a weird experiment with colors. All sorts of fun!
They all show the scrollbar as well. Not quite the Ubuntu overlay, but it still works well. Scrolling using the mouse "wheel" doesn't seem to work for me though (Mac OS X, magic mouse...). I've been changing the Canvas files as well, but nothing major, and I'll push changes when I'm done tonight.
... I suppose I should stop bragging off-topic now.
