CSS3 and Javascript Planetary System
After seeing neography.com's CSS3 transition galaxy I couldn't help but rewrite it using javascript so that it would work in browsers other than Chrome or Safari. Eventually Firefox (maybe IE?!) will support CSS3 transitions and animations as well, but for now, we need a javascript implementation.
I still have work to do on the satellites (moons, rings, etc) so it's a work in progress for now.
