Impress is the presentation package within OpenOffice.org. At first glance, it appears to be the simplest of the key OpenOffice.org components, and also the one that borrows the most look and feel from Microsoft Office. However, delving into its feature set reveals more than a few surprises, including sophisticated animation effects and drawing tools. Impress can also export presentations as Adobe Flash-compatible files, which means that many Internet-enabled desktop computers around the world will be able to view the files, even if they don’t have Impress or PowerPoint installed.
