More fixes.

All of the nastiest bugs are fixed, and everything is looking a lot tighter. 

Some remaining things to consider:
1. The video won't work in Safari until you get an mp4 up there too.
2. The [PG] logo doesn't show up if it's hidden and you resize the window down to mobile view. It's probably fixable with a little more work, but it's unlikely many people will encounter it in the real world, unless they're testing your responsive design.
3. The form is un-fucked, but it still looks a little funny at certain window sizes.

I'm still up for tweaking little things here and there. All told, I think this version is very close to shippable.
