Dune Fun was designed to teach students and adults about dune erosion and creation processes. This section of this dune web site is highly interactive and has many animated illustrations. Because of this, opening these files may be a very slow process if you are using a slow modem. To speed up the interactive process, download the Dune Fun files to your computer and then run them directly from your hard drive. Some computers may also not be able to read the animated files.
