I make GoJS, a JavaScript diagramming library
I wrote a book on HTML5: http://www.amazon.com/dp/0672336278/
It contains chapters dedicated to HTML Canvas, Canvas interactivity and Canvas performance.
Occasionally I write tutorials and performance tips for canvas:

I love those who yearn for the impossible.
