  Favicon alert bubbles▲271

  A javascript library that allows easy manipulation of the favicon to include nice looking alert bubbles. This means that users can pin your site and still see when their attention is needed! It's been done before, but in my opinion not in a way aesthetically pleasing enough for production use. This library also falls back to the standard number in page title approach for browsers that do no support canvas / dynamic favicons. Thoughts welcome.
