Stumbled on this totally cool dynamic galaxy view. The swf file shows the planets and moons moving around their resepected object in space. It is coupled with a speed switch and time indicator. Way cool. Great job on this piece from Dynamic Diagrams. I just love these types of info graphs and dynamic renderings.
