looks good, except for the repo url, as noted in the commit. i'll try to dig up the examples i was using when testing and we can add that.

Agreed, this is just pointing to my repo for now because I'm using it in a project. That should definitely be changed to point to your repo.

Also, commits cc90855 and d07d865 are questionable. Really, the only thing you should need to bring in is the package.json. I had issues using libnoise.js in the browser because if the 'if ( module )' statements, which are fixed by those commits, but it still doesn't end up working as I would expect.
