Welcome to multi-media help. This media is presented in a format that hopefully is viewable by most visitors. However, other formats are available, and they may work with your device if the default format does not. You will see one or more links above the media that lead to separate pages where the content is shown using a different method. Here are the explanations for these links:
SVG stands for scalable vector graphics. This is a relatively new form for drawing diagrams and pictures on a Web page. If your browser is up to date (as of 2011), this type of presentation will probably work for you. This type should work on the iPad.
The video link takes you to a video of the media. This video is shown in a player that should work on about any system: PC, Mac, Linux, iPad, or Android. The video is delivered as HTML5 video if you have a browser that supports HTML5, or it is presented using a Flash player if your browser does not support HTML5 video. It looks and works the same either way.
This link takes you to a Flash animation of the media. You will need a Flash plugin installed in your browser to see this media.
VRML stands for Virtual Reality Modeling Language. It is a 3D viewing environment for the Web. You will need a VRML plugin for your browser to see this medial.
Hopefully your viewing device will be compatible with one of these methods.
