This morning TUAW posted a review of Slidevana. The article, Slidevana provides pro design templates for Keynote, describes Slidevana as “smart collection of slide design that goes way beyond any of Keynote’s built-in templates”. The article also describes Slidevana’s overall design:
From tables to bullet lists to key point images, Slidevana offers a unified design that easily translates into high quality presentations. It’s like a Keynote version of those graphic design and color harmony cookbooks you can purchase at art school bookstores. But instead of general graphic layout, Slidevana focuses on the most common presentation challenges.
