About 99% of all of the graphics, colors, and shapes are vector graphics, meaning that they are easily resized and recolored in the Flash UI. So whatever you cannot set in the XML, you can easily edit in the Flash UI. There is nothing that you see that cannot be easily edited in one way or another. This website loads external .swfs. into the UI of the page. You can work on any page of your own in a separate .fla file and after setting the paths to your complied .swf file in one config.xml file, you can load it into the site! Plus, in the same config file you can also set the transition animation for transitioning your pages both in and out of the site as well as set the width, height, and z-index of your loaded pages. You can also control whether or not to stop the sound playing on the site (if you are loading a page that also has audio, such as the video player).
