Here is a quick vocabulary card concept that I made for a presentation about 5 months ago. The purpose was to communicate some possible utility feature for a new app. The project was canceled soon after.
This was animated entirely with Keynote. I've been using Keynote for many years, and I love how simple it is to animate objects. The secret is the "magic move" transition which takes care of most of the main animations. It works well for basic animations like this, and I've found it helps bring a presentation to life when the subject animate.
Stay tune for some more animations from this collection of features.
