If you don’t already know, KillerLight is the name of the theme I created for this site, and which is available on wordpress.com. Currently it uses JavaScript to do some animation of the header, fading between several images to give the impression of lighting effects. Many people have contacted me (sorry to everyone I’ve not managed to reply to!) about the performance, saying that even on high-spec machines it struggles.
Well, perhaps with the advent of HTML5, specifically the Canvas element, this will hopefuly be improved when I have the time. This new element is designed for graphics rendering, and uses the graphics card to it’s full advantage where possible. This should produce a huge difference in performance. For those without an HTML5 browser, they will see a standard static (non-animated) header.
