Thanks man! It's crazy how many iterations we went through to get it looking good (I've got a blog planned to talk all about it!). It's easily been one of the toughest parts of this whole process. You don't think that you're going to obsess over it as much as you actually do.
It is so crazy that some dude in the UK had a super old web page with the exact solution I was looking for. I can't even begin to tell you how nice it was to find that. Of course, it was still a ton of work, but having the conceptual algorithm really helped.
I wanted to contribute my Javascript implementation to him so he could add it to his collection, but oddly his site has disappeared...
