Find a real-world use of <canvas>, and then try to make it accessible using an image map. The problems I describe will very quickly become quite apparent. (Bonus points if you find a canvas where the interaction is dynamic or animated, or where the painting code uses transforms, both of which increase the difficulty even further.) -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
