Most templates now available for Apple Keynote
The template store now supports Apple Keynote, a drop down menu let's you make a selection between your preferred presentation software. Not all templates could be converted, Keynote is missing the 3D shape rotation feature of PowerPoint that I used in some of the slides.
The only adjustment I made was the font: switching it from PowerPoint's default Calibri to Helvetica Neue for Keynote. I am keen to keep the look and feel of the charts as "standard" as possible to make it easy to integrate the design in the corporate presentation templates that people are using.
The slide above is a layering of 2 images that visualizes a big dam that is under pressure from something. You can use it either to show that something is about to burst, or the opposite, that defenses are strong and holding out well. I love the massive architectural scale of these hydro power installations, especially when you can highlight it with this tiny car driving across it. You can download this dam template here.
Looking for other visual concepts that are similar? You can try and search the store for "forces", "down", or this search "downward" and see what slides come up. That is my longer-term vision: no more boring bullet point charts, and no more searching for "where is that slide that I made 2 years ago", but rather have all the relevant designs ready at your finger tips. The search engine with design ideas is almost as important as the actual design itself.
