A while ago I was working on a personal project concerning various geometric and topological operations on html5 canvas elements. Nowadays it is a bit abandoned but It was a pity to let it go to waste. So I made a public repository on Bitbucket and GitHub.

As of today 19-November-2013 I would be maintaining the github version
