Icons/Lines: This presentation refresh simplifies the current template and pushes focus on the content being presented. The icon library will continue to be utilized, but a refresh will be noticeable with the removal of the dotted lines around each icon, and a subtle color shift. These icons are created to provide a professional, consistent look. When these icons are used sparingly, and in direct relation to the content on the slides, our presentations will communicate and work more effectively.

Note:

Typeface: Arial has been selected as the new typeface for all Novell communications. The following were considered. 1. Our typeface needs to be designed to carry information quickly to the reader.2. It needs to be usable for Novell employees in company correspondence and presentations, as well as for outside vendors for marketing and promotion.3. It needs to easily function on the Linux, Windows and Macintosh platforms. 4. And finally, Arial was created for these exact purposes.
