This is sweet, maybe you could benefit from some of the code I wrote a little while earlier for something super similar: http://polygonz.zaucetech.com/

I guess this is a popular idea, made this one a little while aog: http://polygonz.zaucetech.com/ its pure javascript and canvas and allows any color you want

Weirdly, I had this exact same idea a little while ago and threw something together: http://polygonz.zaucetech.com/ its open source too!
