HTML5 Canvas Drawing Effects
This tutorial shows you how to use canvas to create over a dozen different types of drawing effects. The snippet gives you an option to choose what type of brush you'd like to draw with (choose from one of sixteen different and colorful options!), and it also allows you to clear the canvas as well. It almost mimics the paintbrush or airbrush effects on popular image editing software like Photoshop.
