SVG is by no means a solid game development platform, but it is some interesting browser-based technology which might be useful for game developers to investigate.
Pretty smooth demo :). I see what you mean now, but i was going on the assumption that in a turn based game he wouldn't need to do much transformation, hence, my suggestion to just use pngs and allow the browser to redraw them.
