I recently started working on adding some good-looking brushes to Fabric.js. We've had free drawing functionality for a while, but it was... laughable. Just a simple pencil of varying thickness. Far from anything you would see in those amazing drawing applications popping up in the last few years — Mr. doob's Harmony, deviantART's Muro, or mudcu.be Sketchpad. Freedrawing is one of the strongest points of canvas, so it's a shame not to have something good in a canvas library like Fabric.
