"A Designer's Guide to Web Fonts," PowerPoint and/or Keynote presentation design by FontShop. A design can't get much friendlier and inviting than this! The monoline illustrations, simple colors, and softer sans-serif fonts are easy on the eyes.
"Web Typography: State of the Art," PowerPoint presentation design by Idan Gazit. These slide designs and layout feature rad typography of course. Images and icons are used tastefully, but the text takes center-stage.
"The Power of Social Influence," PowerPoint and/or Keynote presentation design by Harp Advertising + Interactive. Diagonal lines, bold colors, and cutting edge layouts make these slide designs feel very energetic.
