I suspect codepen may have a size limit on how much code can be in a pen. Source is here: https://github.com/MathiasPaumgarten/hair

It does, I know. That's why I said "sorry" :). However - Since I wrote it in AMD I didn't want to put up with concatenating and renaming. If you are interested in the code, check out the git repo. But you are right, I'm not happy to see compiled code on codepen either. I'm such a hypocrite I guess ...

Hey, I'm only saying so because it's cool and wanted to read through it! Checking out the git repository now :)

There is a notice at the top with a GitHub link.
