This looks insanely cool, but it won't render for me. I'm running the newest version of Chrome on Snow Leopard which is supposed to support WebGL, other examples work fine, but I'm just getting a checkered background.
I hate to ask, but did you actually click "Render"? Just clearing away the text that is in the middle when you first load it has exactly that result if you don't click "Render", which is why I ask. It was also non-obvious to me that when I changed fractal types, I had to click "Recompile"; everything else updated live, so I expected that to as well.
Works in Firefox 4. The RC arrives this week. It's finally done.
