This is a truly unique Keynote theme. This one is called – the Burning Moon Keynote Theme. It’s kind of futuristic and apocalyptic, but very cool! I found it on Deviant Art, by user Martz90, if doesn’t mind I’ll probably try to convert some of his other stuff into iWork files for you. He has a ton of great stuff. This is a little different from the other things that we have on Free iWork Templates, but I couldn’t help myself. Its pretty amazing. Enjoy!
If you want to add more slides just navigate to the “Inspector”, and then go to the “Appearance” section and just add an image fill and it will show up.
