Remember how you used to mark important bits of text in books or notes by drawing underlines in them? Now you can create that same effect for text or links on your web page using a bit of SVG. This effect was designed by Michelle Barker.
When you hover over the text you get a neat hand-drawn line multi-line underline for the link.
If you are having trouble with the pen, try the archived copy on GitHub
