My Background <canvas> entered my awareness in 2006 when Firefox v2.0 was released. An article on Ajaxian, describing the transformation matrix, inspired me to create my first <canvas> web-app; Color Sphere (2007). Which immersed me into the world of colors, and graphic primitives; inspiring the creation of Sketchpad (2007-2008) in an effort to put together an application "better than Paint" in th
