TheWebCoder said: "Unlimited" and technology are often at odds when it comes to performance. Each layer uses browser memory and system memory, so the devs will need to find the sweet spot. That's not to say they can't add more layers, but I'd be surprised if they ever said, "go nuts" Uhm, let's be reealistic.. nobody will have more than a handful of layers anyway, even if there would be a possibility to add an unlimited number of layers. You need to fill them with something, after all. Well, unless we could have some crazy parallax effect on it - top layers moving slightly more than the ones below, so when you scroll, you get that 3D feeling. Excuse me for a while, I'm sitting in my corner, drooling.
