Macware today released PowerSlides for Keynote and PowerPoint, offering fresh presentation backgrounds coupled with guidance to deliver clearer messages through the use of slide design templates. PowerSlides feature more than 200 designer backgrounds, over 300 textured backgrounds, 15 progressive backgrounds, and more than 100 pre-formatted slide templates. PowerSlides also comes with 50 template sets that include title, text, and print variations. "Progressive Backgrounds visually show the passage of time or dynamic action as each slide helps guide an audience through your message. This can show the phases of the moon, a human in action, the cycle of a single day, and much more." PowerSlides are available for $40 from Apple Stores and other major retailers.
